Busy, sick, picking up mini-coco from ABQ airport, all those good things kept me from writing. I'm still slightly feverish, but hopefully on the mend. <br /><br />I got the opportunity to drive over to the Los Alamos area on Saturday, to visit the Don Quixote Distillery with a friend. I really like their ports, and the rose wine (roses used in the making, not a pink wine), though somewhat herbal/medicinal, is good when you prefer something a little different. I'm definitely thinking of these for local gifts. The setting in White Rock is quite nice, very close to White Rock Canyon.<br /><br />Afterward, we went for a little walk at the Tsankawi outlier to Bandelier National Monument. The photo below is looking east towards Santa Fe (and the beautiful fall colors in the aspen band) from Tsankawi. The reddish-buff cliffs in the foreground I believe are the Quaternary Tshirege member of the Bandelier Tuff. San Idelfonso and other Tewa pueblos claim ancestral ties to Tsankawi. I found disparate estimates of occupation on various websites, ranging from a vague 1400s to 1400-1550. <br /><br /><div style="text-align: left;"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiDRO5Kg_yZgm9poE6NsY5lgyh59AtktAQtkL0MA-QhgiapGjFwdPB16iqOBW8QNMUpNG-NWSdwTpxtKz3bOYHk21B3vQzbzZH5OYhz-N2K9pxmPf9knZP4ObyCTArGCCxdksieMGk69CE/s1600/002.JPG"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiDRO5Kg_yZgm9poE6NsY5lgyh59AtktAQtkL0MA-QhgiapGjFwdPB16iqOBW8QNMUpNG-NWSdwTpxtKz3bOYHk21B3vQzbzZH5OYhz-N2K9pxmPf9knZP4ObyCTArGCCxdksieMGk69CE/s400/002.JPG" alt="" id="BLOGGER_PHOTO_ID_5527218319479298242" border="0" /><span style="font-weight: bold;"></span></a><br />On the way back, an image of the Pliocene Cerros del Rio basalt overlying Puye fanglomerates. We had just crossed the Rio Grande, upstream of White Rock canyon. The canyon formed by the Rio Grande cutting through the Cerros del Rio basalt (yes, I'm a little late to the basalt columns meme). The canyon has been dammed on at least three occasions in the last 3 Ma both by Cerros del Rio basalts and the Tshirege member ofthe Bandelier Tuff, forming lakes that backed up into the Espanola area.<br /><br /></div><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1HYPynBhRoPSVKWj_NYtBXOuutkcbfgb22gMstUAR8l6PGJvSr8Ykl9XlSM2DeMtKTonC8twSwmN9FDGGaEpRB0PHLDhd5vB7YU7-RaRPxRRnLAEIEFworEuSPqLJn3E2IvnPDK8JWJo/s1600/006.JPG"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1HYPynBhRoPSVKWj_NYtBXOuutkcbfgb22gMstUAR8l6PGJvSr8Ykl9XlSM2DeMtKTonC8twSwmN9FDGGaEpRB0PHLDhd5vB7YU7-RaRPxRRnLAEIEFworEuSPqLJn3E2IvnPDK8JWJo/s400/006.JPG" alt="" id="BLOGGER_PHOTO_ID_5527218309955298034" border="0" /></a><br />At Tsankawi, a lupine still blooms.<br /><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiFzdIIiLuNhBhLAk_0mxqy-VxYobOobiiK10xMNCg1J0tT4WjW3KMPrrElqI5tu2Dgueom2od39XiFyU1sEpYxPpjLuEasku2ZWFxJ2O0fhK-eoxWKaTyZ5j9xeAr7etFu6IjkeTLEQu4/s1600/001.JPG"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 400px; height: 300px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiFzdIIiLuNhBhLAk_0mxqy-VxYobOobiiK10xMNCg1J0tT4WjW3KMPrrElqI5tu2Dgueom2od39XiFyU1sEpYxPpjLuEasku2ZWFxJ2O0fhK-eoxWKaTyZ5j9xeAr7etFu6IjkeTLEQu4/s400/001.JPG" alt="" id="BLOGGER_PHOTO_ID_5527218322908687282" border="0" /></a><br />References: various articles, road logs in : <span style="font-style: italic;">Geology of the Jemez Region II, New Mexico Geological Society Fifty-eighth Annual Field Conference, 2007</span><br /><br />Link: http:<a href="http://www.nps.gov/band/photosmultimedia/tt-vt-intro.htm">//www.nps.gov/band/photosmultimedia/tt-vt-intro.htm</a>coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com2tag:blogger.com,1999:blog-371888302852802442.post-71360049315065916162010-10-06T20:23:00.001-07:002010-10-06T20:26:59.363-07:00Culverts 2: Piping?!!!<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhE7JJ1rd4tGXJdgjAC6Utt0TMGS6B-POdGFQBJHsO95uhYFg_7nvPlz9QiEI17t16XfQe3ATVDgNB3URNix0aMjDdD1LQPHiqxfyUJdbE4nbkoNTID-iUB3CAnEOkOHSgBrzgAIgYfHPI/s1600/untitled.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 400px; height: 297px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhE7JJ1rd4tGXJdgjAC6Utt0TMGS6B-POdGFQBJHsO95uhYFg_7nvPlz9QiEI17t16XfQe3ATVDgNB3URNix0aMjDdD1LQPHiqxfyUJdbE4nbkoNTID-iUB3CAnEOkOHSgBrzgAIgYfHPI/s400/untitled.JPG" alt="" id="BLOGGER_PHOTO_ID_5525139716111848194" border="0" /></a>A friend sent me this photo.

The flow rate varies during the year from less than one cubic foot per second up to around five cfs. The spring is in a limestone formation, whose name I am not sure. The geologic map for the Rosilla Peak quad is in draft form and hard to read. It doesn't include much detail in the mapping on this hillside, either. <br /><br />There are also caves just around the hillside (fenced) that have cultural significance to the Jemez Pueblo; when the Pecos Pueblo was so decimated by disease there were few people left, the remainder joined the Jemez. The Jemez were trying to purchase and remove access to this tract (owned by the state, now) some time ago; I'm not sure if they are still working on it.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkyZ34sqOUo2qAAdtSwopPwf_mFiwH9jI9C5V4-oBgQm9BTzBVhI98ZLPgmZAcCvl4ClAtHOM4Zkxt2kxHPdaU02fAKlqyofM-oSTlEOn5BBtqKU34k7fMjk7P1q2nofKWcFR3q6A5eNQ/s1600/005.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkyZ34sqOUo2qAAdtSwopPwf_mFiwH9jI9C5V4-oBgQm9BTzBVhI98ZLPgmZAcCvl4ClAtHOM4Zkxt2kxHPdaU02fAKlqyofM-oSTlEOn5BBtqKU34k7fMjk7P1q2nofKWcFR3q6A5eNQ/s320/005.JPG" alt="" id="BLOGGER_PHOTO_ID_5523988260361606082" border="0" /></a>When the flow increases, occasionally there is some local hullaballoo about cars driving through the spring flow across the road and increasing turbidity and the sediment load in the Pecos, into which the spring flows, albeit through a very nice wetland complex in between the road and the river (just outside the field of view to the right of the photograph to the left). The increased turbidity in the Pecos is not a good thing, and it does piss off the fishermen and women who have likely traveled a ways to get to what is known as a very good trout fishery.<br /><br />Occasionally, someone will bring up an earthquake somewhere that occurred just about the same time the flow increased. Local knowledge puts it that the flow increase is sourced much more locally (upstream a ways). The rationale is that the flow has, in the past, included fire debris from a canyon about 1/2 mile to a mile upstream that did not occur any further upstream on the Pecos. Presumably, the flow pathways through the limestone include a source in or near that canyon. (Did that make any sense? I'm still a little under the weather.) Nobody knows for sure, as no hydrologic studies have been done on the spring of which I am aware. <br /><br />It's a lovely spot, and well worth a visit. Just drive up the canyon almost to Terrero, turn left up Holy Ghost canyon, turn right and cross the creek toward the campground, and you'll cross the spring flow in a very short distance.coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com1tag:blogger.com,1999:blog-371888302852802442.post-86137779878822103312010-09-27T19:03:00.000-07:002010-09-27T19:23:11.299-07:00Accretionary Wedge #27 - Important Geological ExperiencesI have no pictures for this one, just the vivid, graphic impressions of a 9-year-old living in Seoul, Korea in 1972. I was already in a foreign land, where the pine trees didn't grow like the pines at home. When I first arrived, at age 7, I went through quite a bit of culture shock, from the smells, the sights, the sounds of Seoul when sewage ran down the streams and there was still no subway. My hair got touched everywhere I went (I was blond as a little girl) and always, crowds of people would gather around me to see the little foreign girl. <br /><br />After a time I (mostly) got over that, but visits to art museums and palaces with lots of Chinese art always left me with the sarcasm that only a 9-year-old could have: "Mountains don't grow like that!" That thought crossed my mind every time I would see a Chinese scroll or print with these funny tall mountains that didn't have an inverted "v" shape. <br /><br />That is, until Nixon went to China in February of 1972. Some of the officers who were attaches on the trip were somehow allowed to go to Guilin. And they brought back pictures. And us kids in the 4th, 5th, and 6th grades at Seoul American Elementary School (at the post on Yongsan, for those in the know) were among the first to see them. <br /><br />It blew my mind that day, that mountains did "grow" that way, that the art I had seen was not all wrong. I looked at those slides with wonder and awe. And they inspired a love of landforms and earth processes I've never lost. <br /><br />Wikepedia link to Guilin image:<br /><br /><img src="file:///C:/Users/Deanna/AppData/Local/Temp/moz-screenshot.png" alt="" /><a href="http://en.wikipedia.org/wiki/File:Rio_li_Guilin02.jpg">http://en.wikipedia.org/wiki/File:Rio_li_Guilin02.jpg </a>coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com0tag:blogger.com,1999:blog-371888302852802442.post-26777675404090653432010-09-25T06:53:00.001-07:002010-09-25T07:43:51.446-07:00Saturday Site Visits, Tecolote Creek Falls<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrn82nILz0AZRnSWI5PhVA6UhGfrAjbw9dtkme4VKLp-2lqCfmsJxUV-v1e6xIKrbD9QIYBUOJJYxT0ue372y7G-ecutFDtweg0Do9qPJg28ZS0tMrYohJwkg4raU9FDc3_6tIUQRI_to/s1600/014.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrn82nILz0AZRnSWI5PhVA6UhGfrAjbw9dtkme4VKLp-2lqCfmsJxUV-v1e6xIKrbD9QIYBUOJJYxT0ue372y7G-ecutFDtweg0Do9qPJg28ZS0tMrYohJwkg4raU9FDc3_6tIUQRI_to/s320/014.JPG" alt="" id="BLOGGER_PHOTO_ID_5520849841579916194" border="0" /></a>A few weeks ago, after offering advice to a sand and gravel mining company, I got to do a quick side trip to these falls on Tecolote Creek, near Apache Springs, San Miguel County. <br /><br />We turned off Hwy 84 onto CR B27, for a not unpleasant drive south (this road, even though dirt, provides access for a number of folks living out this way). Took about 10 minutes or so to get to the fall. Views of tires used as small erosional feature bank stabilization and bypassed culverts provided for much humor on the drive. <br /><br />We were hoping there was still a little flow over the falls, but, as you can see, they were dry.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3xdQ-CDLifeGvM3XN-t20EpeBkNXH0GkRR0iEa0sGE-akjHOYnelYPboNQa3jolRkMOnIQeoQuSrtlETlQ9cfDqtmsZBi0lyTb2P00EQ30gvIoAb4u0YcatVgd0eTJUAaBA5DzalLZgM/s1600/015.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3xdQ-CDLifeGvM3XN-t20EpeBkNXH0GkRR0iEa0sGE-akjHOYnelYPboNQa3jolRkMOnIQeoQuSrtlETlQ9cfDqtmsZBi0lyTb2P00EQ30gvIoAb4u0YcatVgd0eTJUAaBA5DzalLZgM/s320/015.JPG" alt="" id="BLOGGER_PHOTO_ID_5520849849280128194" border="0" /></a><br />There were still a few small pools, or tenajas. I've also seen usage of aguaje applied, but don't have a very good translation of that term.<br /><br />The creek, in this area, loosely follows the axis of the Tecolote Creek anticline (plunges to southeast). In the upstream reaches, the overlying San Andres has eroded away, largely exposing the underlying Permian Glorieta Sandstone. As one follows the axis of the anticline to the southeast, more of the younger formations are exposed. The falls occur pretty much where Tecolote Creek starts eroding through the Permian San Andres limestone, to spectacular effect. <br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOi46cIcPBghEC0CnhMZ9kfycv6WmDCyNH14TAhnG7ZO5GNKahJRZpfn7F9QeaWd6bnJO8GHoFskbM7BsApetFyKT98mPnAlU70sTNZRJ4e9oZNb8gahTMHC9m9Oy1hu7cYRzPNmKhlL0/s1600/017.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOi46cIcPBghEC0CnhMZ9kfycv6WmDCyNH14TAhnG7ZO5GNKahJRZpfn7F9QeaWd6bnJO8GHoFskbM7BsApetFyKT98mPnAlU70sTNZRJ4e9oZNb8gahTMHC9m9Oy1hu7cYRzPNmKhlL0/s320/017.JPG" alt="" id="BLOGGER_PHOTO_ID_5520849861049316898" border="0" /></a>A view looking upstream.<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYXD3S-lEzx9JGFq-d36cY2EKM0C_2huDS1m63xVhkJn406F6CkjUU_pc3SEJdJ4CihN0VgW0Y261r_K7l79FTZGg289oVQ68p-6YZ9rHXb_MEXTWm6QtOOAmA7e-7sxsQ-qIbV70b7Vg/s1600/018.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYXD3S-lEzx9JGFq-d36cY2EKM0C_2huDS1m63xVhkJn406F6CkjUU_pc3SEJdJ4CihN0VgW0Y261r_K7l79FTZGg289oVQ68p-6YZ9rHXb_MEXTWm6QtOOAmA7e-7sxsQ-qIbV70b7Vg/s320/018.JPG" alt="" id="BLOGGER_PHOTO_ID_5520849864978684722" border="0" /></a><br /><br />A view of the top from below.

Culverts are a necessity for roads and other short crossings. It is also important that culverts be appropriately sized and placed within/on the substrate. Culverts can also have incredibly damaging consequences on the aquatic environment if improperly sized/placed. Even bad culverts in ephemeral streams can have downstream consequences (via excess sedimentation from erosion, for example). I come across a lot of bad (and some good) examples in my travels and am happy to share them for discussion. <br /><br />This is a set of culverts on an small, ephemeral arroyo near Apache Springs, NM. Normally, these small (-ish) arroyos only run in response to heavy rain events and when they do flow, they often flow very big. They are characterized by either upland or no vegetation, and in this neck of the woods, are easily erodible. <br /><br />The landowner, at some time in the past, installed the series of five culverts in an attempt to provide a crossing that would work during inclement weather. You can also see that the culverts have no road base or other roadway material on top of them. It's been eroded over time to the point of being non-functional. If you look to the right of the photo, you can sort of see the ad-hoc at-grade crossing that the landowner has used to bypass the failed culverts. When we drove by, I had my colleague stop and back up so he could see it, as well. We both laughed and said this landowner had a case of the "aww, f***its" with respect to the culvert. It's a pretty common sight, here in the low-income, rural southwest.coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com3tag:blogger.com,1999:blog-371888302852802442.post-60783315483198176282010-09-18T08:57:00.001-07:002010-09-18T10:34:52.664-07:00Saturday Site Visits, Folsom Falls on the Dry Cimarron<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6-oBcHLDacyEhMBLz92ko_Wq4a1UiC1GObEcWcx2HImj-ODmjRANMmM2dzUW42Z0m8dqlQt5TQbaP_e13Xq35xdBd0ck5q6yWH0p2tX-aZ9IJtisEPpPFfTlfwpcQjl4XEHfluF1NCCE/s1600/017.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6-oBcHLDacyEhMBLz92ko_Wq4a1UiC1GObEcWcx2HImj-ODmjRANMmM2dzUW42Z0m8dqlQt5TQbaP_e13Xq35xdBd0ck5q6yWH0p2tX-aZ9IJtisEPpPFfTlfwpcQjl4XEHfluF1NCCE/s320/017.JPG" alt="" id="BLOGGER_PHOTO_ID_5518287224378638994" border="0" /></a>In June, I had the opportunity to look at a restoration project on the Dry Cimarron River, near Folsom, NM. On the way back, we stop for a quick look at Folsom Falls. I wished I had the chance to stay longer and really hike around the fall for better vantage points, but we had a long drive back to our respective starting points.<br /><br />Folsom Falls is formed by the Dry Cimarron River flowing over a lip of what Baldwin and Muehlenberger identified as the Baby Capulin basalt of the Raton-Clayton volcanic field (RCVF). The RCVF comprises mostly basaltic to nepheletic cinder cones, andesitic to dacitic necks and domes, and a very cute shield volcano named Sierra Grande (Baldridge, 2004). The RCVF is Pliocene-Quaternary in age, with volcanism commencing around 7.2 Ma and ending with the Capulin eruption around 60ka. RCVF is approximately contemporaneous with the Ocate Volcanic field, about 50+ miles to the west and is on the Jemez lineament, a zone of volcanism extending from the Springer volcanic field in east-central AZ to the RCVF. The Jemez lineament cuts across tectonic provinces, and as such, its origin is not well understood (Baldridge, 2004).<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi8uZRQoKq9enjlRKbkudf6UsE2VHtZcixdji821Pbk3SsbPurVO468G9lCq2Eog_ZMWfoN9Eil0zqZeveIU0ul5PM3tGP5onXu1XR__HoYWUL13xhyphenhyphen8kp5nPzBJ5VC1qpg6qhBoLtmc58/s1600/021.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi8uZRQoKq9enjlRKbkudf6UsE2VHtZcixdji821Pbk3SsbPurVO468G9lCq2Eog_ZMWfoN9Eil0zqZeveIU0ul5PM3tGP5onXu1XR__HoYWUL13xhyphenhyphen8kp5nPzBJ5VC1qpg6qhBoLtmc58/s320/021.JPG" alt="" id="BLOGGER_PHOTO_ID_5518284727437926898" border="0" /></a>The view above looks south across the falls. The view to the left is looking downstream. The riparian habitat is well-developed, suggesting the surrounding ranchers aren't letting their cows in to graze (yay!). However, the local kids apparently use it as their party spot, judging from the amount of broken glass and other anthropogenic detritus.<br /><br />I like the area, because it is very reminiscent of my home country in eastern WA, with lots of basalt, grasslands and the occasional hidden ponderosa stand, much like the landscape near Spokane, WA. There's a Spanish word, querencia, for a place from which one draws strength, which tugs at one's heartstrings. This area of New Mexico is definitely one of mine.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYcVs_HOkU5w_0eXMaRB43au8M5bc3GMna3VGNtS-HQywM5_roFlKKmVhUtdFVqWT8Gea8hu7JggkB8WI6kaIXEsz0re4ozhshQ0fdTgZzC2cz1VURpEowERAABHLLua8yhg8t-0V3dTI/s1600/GoogleEarth_Image.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 228px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjYcVs_HOkU5w_0eXMaRB43au8M5bc3GMna3VGNtS-HQywM5_roFlKKmVhUtdFVqWT8Gea8hu7JggkB8WI6kaIXEsz0re4ozhshQ0fdTgZzC2cz1VURpEowERAABHLLua8yhg8t-0V3dTI/s320/GoogleEarth_Image.jpg" alt="" id="BLOGGER_PHOTO_ID_5518286662638092690" border="0" /></a>Google Earth image of the location.<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmW4ThkPdV6egA8i9hsrBwK6H_Cx0qP84IBhVAx474kJouPNWNbUaBBA4T9fCaiYrYaJ5S1ZE6WYaowKIID55sxUqCUtnE9YGkOCuv7IS07nKw46v6m3JT2RFqsJVXeYU-SiawCUC8LS0/s1600/Folsom+Falls+Stratigraphy.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 220px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmW4ThkPdV6egA8i9hsrBwK6H_Cx0qP84IBhVAx474kJouPNWNbUaBBA4T9fCaiYrYaJ5S1ZE6WYaowKIID55sxUqCUtnE9YGkOCuv7IS07nKw46v6m3JT2RFqsJVXeYU-SiawCUC8LS0/s320/Folsom+Falls+Stratigraphy.jpg" alt="" id="BLOGGER_PHOTO_ID_5518303362092926578" border="0" /></a>Baldwin and Meuhlenberger sketch of Folsom Falls stratigraphy.<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Link: <a href="CVO%20Capulin%20Volcano"> http://vulcan.wr.usgs.gov/Volcanoes/NewMexico/Capulin/VisitVolcano/framework.html</a><br /><br />References: <br /><br />Baldridge, W.

Sometimes there is enough local history/knowledge to get a very good idea of when major landscape change occurred (as in the case of the Dry Cimarron), in others you can make inferences from historical activity, but it's difficult to derive specific dates of change.<br /><br />In both these cases, the specific change has been incision due to anthropogenic changes to the landscape combined with flood/erosion events. The Dry Cim has been heavily grazed in the past, and had specific flood events that caused channel avulsion/incision to bedrock in the location where my photos were taken.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvpo_-sH1gq1EM-J6xq2gtGB3D6mJ_hofivnvj63ScLKk5ty4LXDhtH2yGxSs4aKMC9FqzCzqeQHTsCDVJIy1Sz8hAwoJokNJGcVeCUMD67EENH7mUc4wA9XdbR9vPOG-cVzsDTWTSy2U/s1600/004.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvpo_-sH1gq1EM-J6xq2gtGB3D6mJ_hofivnvj63ScLKk5ty4LXDhtH2yGxSs4aKMC9FqzCzqeQHTsCDVJIy1Sz8hAwoJokNJGcVeCUMD67EENH7mUc4wA9XdbR9vPOG-cVzsDTWTSy2U/s320/004.JPG" alt="" id="BLOGGER_PHOTO_ID_5483400992055973906" border="0" /></a>This photo shows the relict channel, with fine-grained sediment accumulation. One might think that it is a far-in-the-past feature, until you start talking to the landowner and/or folks who know the local hydrograph. Though one would need to age-date material in the relict channel to get an actual date range of the channel deposits, it's quite possible that it may be quite young. There was a ripper flood in 1910 or so, and the rancher indicated that floods in the 40s and 50s caused an extensive amount of incision - maybe 15-20 feet or more (down to bedrock in this location). So, much of the landscape change isn't actually in the far distant past. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhX_Wl3F_N-WK64i0ASTXHU2SCqPA7s6m1WmOIrkyUMqdNov4qpF8jAXAorNAPJp6LDcl-m4RM007OdO0HJWEiJN4RStlmqjU6LXdi6JIRDevwRS0Yx95V0_ojJMVdjShfv7uJBANPxGi0/s1600/002.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhX_Wl3F_N-WK64i0ASTXHU2SCqPA7s6m1WmOIrkyUMqdNov4qpF8jAXAorNAPJp6LDcl-m4RM007OdO0HJWEiJN4RStlmqjU6LXdi6JIRDevwRS0Yx95V0_ojJMVdjShfv7uJBANPxGi0/s320/002.JPG" alt="" id="BLOGGER_PHOTO_ID_5483588316247629794" border="0" /></a> The wider view of the above. It is interesting to note that the sediment in the relict channel is mostly clay-to-sand. Just below the relict channel in this photo is a large gravel bar deposited last year, mostly cobble-sized grains. I saw nothing that size in the relict channel.<br /><br />The rancher here has reduced his herd from about 1200 to 500 head, and has mostly rested this reach for the past 4 years. The resulting riparian and fluvial changes from the release of grazing pressure have been phenomenal. He has beaver dams/ponds and a well-wetted, vegetated channel bottom, increasing bank storage and aquifer recharge. It's unlikely that the system will aggrade back to its original, pre-grazing, agriculture and logging elevation, but it is in much better condition than I had hoped before I went out there. It helped to have a very wet winter for this region.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgWyi-N8_GyktSr3Vty8_o0VO84rEMKev50FmfWjHV5RIeygO-coi1-mR0LAhD8e0DzeB_4zGiKqIiXv8otT8X523KGFCPlwbLnM1_1DOXoko6gBFxs9CS1BG0Iq_GoJH-Wa3DNO7t7irY/s1600/014.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgWyi-N8_GyktSr3Vty8_o0VO84rEMKev50FmfWjHV5RIeygO-coi1-mR0LAhD8e0DzeB_4zGiKqIiXv8otT8X523KGFCPlwbLnM1_1DOXoko6gBFxs9CS1BG0Iq_GoJH-Wa3DNO7t7irY/s320/014.JPG" alt="" id="BLOGGER_PHOTO_ID_5483402123288739954" border="0" /></a>We also talked a lot about wetlands, and what anoxic environments are and the soil columns/profiles that occur in these environments. It just so happened that there was a big grey blob of soil on the opposite slope/bank of the relict channel. It was a splendid opportunity to discuss hydric soil indicators such as gleyed soils and oxidized root channels, even if relict. In this photo, you can see the oxidized root channels that occur when roots of hydrophytic plants carry oxygen down into the reduced environment. Rust then occurs along the root channels. In this instance, they are pervasive through the entire exposure. This blob of former wetland is also about 15 feet up from the stream bottom. Again, little grain size larger than sand. There was also a lens of shells near the bottom, and frequent scatterings of charcoal throughout, indicated upstream or adjacent fires. The three of us there that day loved the fact that even without a lab, a handlens, or a rock hammer, we could infer such a great deal about the landscape.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhiLFYdoMvZWfN4EY4pE9WnT0aX93i3N0uUQE30eYzejOj3krovMiCbHnsIKLTOAyuhrvLz8lNFoLZ4u7SjG8BZFpdBRUUIIPmTLJndZ5Xb5X7_aw_SIbAj7TvRr9uTGj1SpF4aikxVfLY/s1600/030.JPG"> <img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhiLFYdoMvZWfN4EY4pE9WnT0aX93i3N0uUQE30eYzejOj3krovMiCbHnsIKLTOAyuhrvLz8lNFoLZ4u7SjG8BZFpdBRUUIIPmTLJndZ5Xb5X7_aw_SIbAj7TvRr9uTGj1SpF4aikxVfLY/s320/030.JPG" alt="" id="BLOGGER_PHOTO_ID_5483402128208134642" border="0" /></a>Speaking of relict wetlands, at Gold Creek in Valle Vidal, I got this great bank shot that's actually about 8 feet tall from stream bed to top-of-bank. Below the most recent soil column at the top, you can see a well-reduced horizon. Though I wasn't able to get a good close-up, it too has relict oxidized root channels and other hydric soil features.<br /><br />Gold Creek had intensive logging in the past, as well as intensive grazing pressure prior to its acquisition by the USFS (it's still grazed, but I don't think as heavily). Looking at the surrounding landscape, we all surmised (me, especially) that it was likely that this drainage and others like it likely had fens at the extreme headwaters, that have now been incised and drained due to the landscape changes. This creek is now incised about 10-12 feet, but the channel bottom seems to be recovering to the point that it is forming an E-type channel. [We kind of puzzled about the gradient, though. Seemed too steep for an E, but my thought is that the source material grain size is too small to support any kind of a step-pool environment that the gradient would suggest. Crappy weathering volcanics, I think.]<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5YZ7ziL5krUu6gtGA0KGhSj3zPPi9ztpau2CDH74b5vFi8zxFnBYtekHyzfuu2E401ZJPHnA3XouWRLkWJ2ELR1aSYIN2C15-pAHd6uZZ8Wt5udXY4W6hZISDRVcgmxBjCVPfmcJ-SDs/s1600/029.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj5YZ7ziL5krUu6gtGA0KGhSj3zPPi9ztpau2CDH74b5vFi8zxFnBYtekHyzfuu2E401ZJPHnA3XouWRLkWJ2ELR1aSYIN2C15-pAHd6uZZ8Wt5udXY4W6hZISDRVcgmxBjCVPfmcJ-SDs/s320/029.JPG" alt="" id="BLOGGER_PHOTO_ID_5483601238532917122" border="0" /></a>Looking downstream towards Comanche Creek. There's probably about 200 or so feet of drop between the photo point and the confluence with Comanche Creek. <br /><br />I'm amazed everytime I venture into the field about how much of an impact we have had on our environment, even on a little stream up at 9500 feet. I'm also amazed at, and thoroughly appreciate the dedication of the people I work with to restore these landscapes, from the rancher on the Dry Cim, to the folks working here. I may get frustrated on a day-to-day basis, but this, and they make it all worthwhile. <a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhiLFYdoMvZWfN4EY4pE9WnT0aX93i3N0uUQE30eYzejOj3krovMiCbHnsIKLTOAyuhrvLz8lNFoLZ4u7SjG8BZFpdBRUUIIPmTLJndZ5Xb5X7_aw_SIbAj7TvRr9uTGj1SpF4aikxVfLY/s1600/030.JPG"><br /></a>coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com1tag:blogger.com,1999:blog-371888302852802442.post-53847208398898456272010-06-13T11:19:00.000-07:002010-06-13T19:51:44.248-07:00What's Blooming in the Yard?I have a lot of wildflowers coming up in the garden.

Taylor, a composite volcano north of Grants, NM. It was active approximately 3.3 to 1.5 million years ago, and overlies Cretaceous Interior Seaway sediments. The OF-GM-186 for the area is unavailable from the New Mexico Bureau of Geology and Mineral Resources at this time, so its difficult for me to tell you which of the Cretaceous sediments are exposed in my photos, but I do assume they include the Mancos Shale in one of its forms.<br />Mt. Taylor is sacred to most of the Native American tribes and pueblos in the southwest and much of the surrounding mesa-tops and the mountain itself have recently been designated a traditional cultural property, requiring both tribal and State Historic Preservation Officer consultation for federalized projects.<br />This designation makes uranium exploration and development more complex on private, state and federal lands. The price of uranium has risen in the last few years, making extraction more economically feasible, but the cost of environmental evaluation, permitting, and consultation must be absorbed into development costs. Though exploration companies may balk at the process, it's the cost of doing business in the area.<br />As an aside, the uranium source is mostly in the Jurassic Morrison and Todilto formations (Grants Mineral Belt), which do not surface in the immediate area where I was (though there has been considerable exploration, mining and milling on the east side in the past).<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIh3hGYjkjEYD0w-NZRkHd_Ak5ZdKtVIOotasMaKi7141oYRxrQhRd6vpOGUZA5-3rOj4SAD2rR_0c79uxGclgjAJqZbXUOgnVgBL2prLDpNIZly2zWASMVTrMizcoKeeQzD_skthWr40/s1600/018.JPG"><img style="float: right; margin: 0pt 0pt 10px 10px; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIh3hGYjkjEYD0w-NZRkHd_Ak5ZdKtVIOotasMaKi7141oYRxrQhRd6vpOGUZA5-3rOj4SAD2rR_0c79uxGclgjAJqZbXUOgnVgBL2prLDpNIZly2zWASMVTrMizcoKeeQzD_skthWr40/s320/018.JPG" alt="" id="BLOGGER_PHOTO_ID_5468904485323891746" border="0" /></a><br />Photo 1 is a dome/neck on the southeast side of Mt.

I first went with the ex on a planning trip for a GSA field trip he was organizing for the Salton Trough and Sierra al Mayor in Baja, way back when. I loved it on that trip, and still do.<br /><br />In 2005, I had some field work in Coachella Valley, on the Whitewater River. We all had some extra time, so we decided to hike up to Palm Canyon at the end of our work day. It's on the Agua Caliente Reservation, so you have to pay to enter the park, but it's well worth it. The first photo shows the view from the upper parking area northeast towards Palm Springs with the Little San Berdoos in the way background (the thin grey line on the horizon).<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikp_8N0CW9ecksbkPPZdX_ytkABk7KTk02B_8gRk75chX_GYYFETEUiHtUA12JiGZfIrVK-K20vbJrmFcyupZGksvOOCp4k-gbd3bQ4UoiR6ToBGuVNeD8JrIBmcgrXsUtr-EaL52pjxg/s1600/PC+Side+Cyn+wtrfall.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikp_8N0CW9ecksbkPPZdX_ytkABk7KTk02B_8gRk75chX_GYYFETEUiHtUA12JiGZfIrVK-K20vbJrmFcyupZGksvOOCp4k-gbd3bQ4UoiR6ToBGuVNeD8JrIBmcgrXsUtr-EaL52pjxg/s320/PC+Side+Cyn+wtrfall.JPG" alt="" id="BLOGGER_PHOTO_ID_5467973022863973474" border="0" /></a><br />This is a waterfall in a side canyon to the main canyon. The stream has carved smooth notches into the boulders making up the canyon walls and floor. As we hiked out from this side canyon, we all felt an earthquake, one of about three that day, if I recollect correctly.<br />Though it was a pretty warm day out (as summer days in Coachella usually are), it was cool and misty in the side canyon.<br />The hike up the canyon is spectacular, both geologically and botanically. The palm oases were well-managed as a food, water, clothing, and shelter source for the Coachella Valley tribes (as well as AZ tribes with access to oases). Plant, bird, herp, and insect species pretty much abound. There are a few good references, but Jim Cornett from the Living Desert Museum in Palm Desert, has published quite extensively on the natural history of the Lower Coloradan desert.<br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkAYiLCrKaLixxXIRLznI6QIQ_13Z3S59pr8Y-S3UADLC4JfFeTcIMZ76fwcY1-HqT8Bplcr9D1APm-lctEJcyFQYfMrmFYhwafAwDqx0npe7kiO-vnnEyd3rG00NfexSe0PGJXhQudcI/s1600/PC+Side+Cyn.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 240px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkAYiLCrKaLixxXIRLznI6QIQ_13Z3S59pr8Y-S3UADLC4JfFeTcIMZ76fwcY1-HqT8Bplcr9D1APm-lctEJcyFQYfMrmFYhwafAwDqx0npe7kiO-vnnEyd3rG00NfexSe0PGJXhQudcI/s320/PC+Side+Cyn.jpg" alt="" id="BLOGGER_PHOTO_ID_5467973019273156626" border="0" /></a>Hiking down to the side canyon, just before the earthquake. Palm Canyon is also home to a primary fault in the Santa Rosa Mylonite zone, the Palm Canyon Fault. For about a couple miles or so, as you drive south from Palm Springs to Palm Desert, you can see the deformation of the granodiorite wane as you get closer to the edge of the deformation zone. The fault trends southwest-northeast, and the deformation (if I recollect correctly and please correct me if I misremember) is evident primarily on the southeast side or upper plate.<br /><br />This side canyon is in the lower plate, and has relatively undeformed geology, as compared to the other side of the canyon.<br /><br /><br /><br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgHnVWLYSf8Jhp3_oXTqODrwcl7j4WD_SJ3AXoSp8okjeOcyn1bMWOuHiiUGA-JohFQMXEc7C6nbh1WxtE871AihzvUweHPjly8Xg3hrLizPhPCm0vDDkeP5yRTYFA2p47-zdhlxkxObb0/s1600/PC+Mylonite.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgHnVWLYSf8Jhp3_oXTqODrwcl7j4WD_SJ3AXoSp8okjeOcyn1bMWOuHiiUGA-JohFQMXEc7C6nbh1WxtE871AihzvUweHPjly8Xg3hrLizPhPCm0vDDkeP5yRTYFA2p47-zdhlxkxObb0/s320/PC+Mylonite.JPG" alt="" id="BLOGGER_PHOTO_ID_5467973035989268562" border="0" /></a>This speaks for itself.

There was snow down to between 8-9K feet. It's now between 9-10K feet, with bare stone showing on most of the high peaks. Most of the lower snow is now gone, and we've reached, essentially, the early low snow peak runoff. Many of the streams draining the Sangres have reached near bankfull. It's hard to tell what the rest of spring will bring. A hard warm rain on the remaining snowpack will bring a rapid peak; a gradual rise in temp from now til June will slowly melt the remainder. All the folks I talk to prefer the latter. Better for towns with constrained streambanks, better for farmers dependent on acequias to water their fields, better for the riparian habitat to thrive through summer. <br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAVscsCY-yNNFS27lE_Njdm5At52Yzyd7ZLVbRK9WmdM_-s6C6kxM3VPLdmxmeZ3zoP3wBC4cciCftnQALaEny2LRp2anL4BdEMpbqXn-1uEWxPnztHHOOb1biXGDhuNya4zHnsLxMLKA/s1600/005.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAVscsCY-yNNFS27lE_Njdm5At52Yzyd7ZLVbRK9WmdM_-s6C6kxM3VPLdmxmeZ3zoP3wBC4cciCftnQALaEny2LRp2anL4BdEMpbqXn-1uEWxPnztHHOOb1biXGDhuNya4zHnsLxMLKA/s320/005.JPG" alt="" id="BLOGGER_PHOTO_ID_5465389125270700978" border="0" /></a>Last week, I visited a very overwound meander on El Rito de la Vaca. We all stood around and scratched our heads about what to do, and we included a geologist, stream ecologist/geomorphologist, aeronautical engineer, and local rancher. A fire a few years back resulted in floods that dumped a boatload of sediment in the valley, messing with equilibrium and setting this meander up for an avulsion. This would create some awful problems for the rancher, including wiping out his only access as well as the forest road providing the main valley access. The final result? We said to contact the head of the local watershed group and get recommendations for a good hydrologist skilled in natural channel design work who can carefully evaluate the reach and design an appropriate solution. Maybe the watershed group can come up with a grant project (there's one more overwound meander just like this immediately downstream) to help defray the costs. And yes, it was snowing.<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtp16ESIBkJNgSCrCks9i_lHJK8hD9LMDUDege4CmvsLokWdXxQF63jHKurqRWq-_ynOzzvhNRuduJ8Ecfr1zF27-Mt2wf6fgpdOLR2ep_Kuxf5YXwMrv1jmYAK6x0RiYOf8TDv8jEWUI/s1600/045.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 320px; height: 240px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjtp16ESIBkJNgSCrCks9i_lHJK8hD9LMDUDege4CmvsLokWdXxQF63jHKurqRWq-_ynOzzvhNRuduJ8Ecfr1zF27-Mt2wf6fgpdOLR2ep_Kuxf5YXwMrv1jmYAK6x0RiYOf8TDv8jEWUI/s320/045.JPG" alt="" id="BLOGGER_PHOTO_ID_5465389132744191858" border="0" /></a>Last, this is the first Persian tulip to flower in my yard this spring.

We've probably had between 6-7 feet total over all the storms we've had at the house, since October. The last of that just melted last week. It's been hard on me, on the kid (and even the dog) schedule-wise, workwise, schoolwise, and otherwise. Only the SO has been okay with the long, hard winter we've had this year. But, he's a mountain man, so it's to be expected.<br /><br />I'm a SoCal girl, though, and these hard winters are equally hard on me. Six months of snow and cold weather is more than enough for me to want to bolt to a warmer clime. But I won't, because I quite like NM, and really can't think of taking my daughter away from what's really her home, now. I can't fathom trying to bring her back to an urban environment and expect her to thrive as well as she is here on our little acre of ponderosa/pinyon-juniper. She's very comfortable in her rural, forested environment. I'm getting there, now that (ahem) the worst of winter is over and I can at least wear sandals occasionally.<br /><br />I think it would be fine with all of us, really, for winter to be over, and to have the apple trees blossom, the penstemons bloom, and green grass abounding enough to make me sneeze.

The drive up was beautiful, as the east side of the Sangres always is. Fortunately, I had enough time on the drive home to stop and take pictures of Coyote Creek reaching bankfull during the spring freshet.<br /><br />I start at the point where Coyote Creek first crosses paths with Hwy 434,near Black Lake Resort. I'm still trying, sporadically, to figure out the local geology. In a nutshell, 434 traverses Jurassic, Triassic, Permian, Pennsylvanian, and Missipian seds in the south end of Moreno Valley, to (?) Pig-Nog and Quaternary basalts in Guadalupita Canyon, to Precambrian metamorphics on the west side of the Crestone anticline and more JTPPM on the east past Guadalupita, once you get to the flat (more or less). The Crestone is a near-vertical outcrop of JTPPM along one of the main Sangre de Cristo uplift faults, the Romero Fault. It extends from near Guadalupita south to past Las Vegas (the other one) and transitions from the Romero Fault to the Hermit Peak Fault. It's a way cool structural feature of the landscape and characterizes the drive north from LV to Angel Fire, at least for me.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4tvJqerfglxlv6XJAV4VHlHDHVl2n7Vct3sy4vQnIynJq07LJdUPjFWpRGRFPRn6IyK0MLwbxoEO3WDa-8gA2PbqIeqf6WmzVhCiIfeZye4kFx1w_KH_7lyQVGv2y4qUgbHzHMBx9Jjo/s1600/010.JPG"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4tvJqerfglxlv6XJAV4VHlHDHVl2n7Vct3sy4vQnIynJq07LJdUPjFWpRGRFPRn6IyK0MLwbxoEO3WDa-8gA2PbqIeqf6WmzVhCiIfeZye4kFx1w_KH_7lyQVGv2y4qUgbHzHMBx9Jjo/s200/010.JPG" alt="" id="BLOGGER_PHOTO_ID_5457978200577240594" border="0" /></a>This is where Coyote Creek first encounters 434, one of many xings.

This is near Las Vegas, NM, on the east side of the Sangre de Cristos Mountains. Luckily, I recently purchased and have been perusing the NMGS "Tectonic Development of the Southern Sangre de Cristos Mountains, New Mexico", so I actually know a little bit about what I got to see.<br /><br />West of Las Vegas, the Gallinas River has cut through the Crestone Anticline to expose some of the Precambrian metamorphic and igneous intrusive rocks in an area between the Crestone upstream and west to around Trout Springs. This exposure, and the bedrock-controlled river substrate (an F in Rosgen parlance), make this a great place for a stream gage.<br /><br />The Precambrian rx have been well-sheared and folded as observed in their exposures along the faulted frontal zone of the Sangres uplift. In the first photo, you can see the gage equipment box, and the folded Precambrian adjacent to it. The picture barely does it justice.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAe76k8Z1-nENx5bUIhOy7uVHU18z2SEZtQQc9Bmb_S8FbtiUF1crawiT4jQPohu8jvzlf-Mcz30Ok91GjGdTJc84WrEGoqd6qLrwrk_x8UIU5icKAidAfDOJYbPK0u8UvhIILUlaE4Ts/s1600-h/PB120007.JPG"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 150px; height: 200px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAe76k8Z1-nENx5bUIhOy7uVHU18z2SEZtQQc9Bmb_S8FbtiUF1crawiT4jQPohu8jvzlf-Mcz30Ok91GjGdTJc84WrEGoqd6qLrwrk_x8UIU5icKAidAfDOJYbPK0u8UvhIILUlaE4Ts/s200/PB120007.JPG" alt="" id="BLOGGER_PHOTO_ID_5403994502315202482" border="0" /></a>A shot upriver from the gage station. The canyon is steep, with poorly- to-undeveloped riparian areas, clearly due to the lack of flood terraces. This changes immediately downstream of the gage station. Between the road grade and areas of less-cohesive, more mafic, weathered zones (fault splay, maybe? - I don't do structure for a living), the river has a greater ability to form riparian habitat/flood terraces.<br /><br /><br /><br /><br /><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTqU8eUXpVn4q0QDio5v8gxVmWVDIVY4NdRhBCcgZ_w8BO_5rjB8K5kmJQfzPNfhCe0NHKgdhvDaGxDv9QDJUGJcEZq5QTDGWoL9eWYCUIG-8wVlUOJZEKOnp7xAXZE1bzhLTxar5b5QI/s1600-h/PB120010.JPG"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 150px; height: 200px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTqU8eUXpVn4q0QDio5v8gxVmWVDIVY4NdRhBCcgZ_w8BO_5rjB8K5kmJQfzPNfhCe0NHKgdhvDaGxDv9QDJUGJcEZq5QTDGWoL9eWYCUIG-8wVlUOJZEKOnp7xAXZE1bzhLTxar5b5QI/s200/PB120010.JPG" alt="" id="BLOGGER_PHOTO_ID_5403996980915782114" border="0" /></a>Here's a shot of the near-vertical Precambrian with a boudin of felsic material. This is just downstream of the gage, in the canyon wall/roadcut.<br /><br />A little further down-canyon (east), a well-weathered zone of mafic material interspersed between the more competent rock. The mafic was easily crushed by hand. It's very similar to the exposure of the Romero fault zone near Mora (post to come), so I wondered if there might be fault splays along this stretch. There aren't any noted in the references I have, but this stretch also has restricted access.<br /><br />I should note that this location is also occupied by northern leopard frogs, petitioned for listing under the Endangered Species Act. The person accompanying me had surveyed for them in the past, and had, with others, determined that the frog occupied adjacent rock pools and wetter zones; habitat much more favorable during lower water years. During freshet or high water years, this habitat would be inundated, lowering the species' ability to reproduce. When the habitat is well-exposed and well-wetted, the species would thrive.<br /><br />We had a fine time exploring the canyon and discussing the habitat and hydrology drivers. I was heartily reminded of a friend's comment (Josh Collins, who works for the San Francisco Estuary Institute and whose wife was a grad student of Luna Leopold) that habitat occurs at the intersection of hydrology and geology. The Gallinas at the USGS gage is a fine example.coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com2tag:blogger.com,1999:blog-371888302852802442.post-51334810708633928152009-10-30T04:17:00.001-07:002009-10-30T05:08:58.130-07:00It should be perfectly fine to prove your restoration works...I recently was made party to complaints regarding regulating agencies, well, regulating. <br /><br />In this particular instance, the colleague (doesn't work with me, but is in my industry) was complaining about post-construction monitoring requirements being imposed on in-stream restoration projects. They weren't particularly onerous, just some longitudinal- and cross-sections as well as photo-monitoring, with an annual report for three to five years.<br /><br />I fail to understand why my colleague was upset that he might have to assure the regulators that his project would do what he said it would do. First, any impact, whether beneficial or adverse, is still an impact, and you need to prove to the agencies that what you're doing is appropriate and feasible and won't cause lasting harm. Second, they quite have the authority to place conditions on permits that they issue in order to assure that the impacts are what they call "minimal." Third, restoration projects fail. Sometimes they fail big, sometimes they fail small. Finally, although I've come across some pencil-pushing dorkbutts, most of the regulators I've worked with are fair, consistent, and very concerned about the overall health of resource that I'm proposing to impact.<br /><br />My recipe for a succesful application and project:<br /><br />1. Give your local regulators a well-described and depicted project. What's obvious to you is not necessarily obvious to the harried regulator who has 30+ people clamoring for their permits, so you need to make it obvious in your submittal. Quantify the impacts, the need for the project. What's the land use history of the watershed? Why is the stream impaired? Do you have a reference reach that you're trying to emulate? Give them clear, measurable performance standards for your project and tell them when and for how long you will monitor, and tell them when it will be successful. Most agencies have brochures or checklists for complete applications; use them.<br /><br />2. Be ready and humble enough for all sorts of questions regarding your design and the need for the project. Prepare for potential changes/post-project fixes in your budget and design.<br /><br />3. Watch your contractors during construction, and put clear damage/non-performance clauses in your contracts. I've heard of contractors driving up and down a narrow stream looking to see how high the splash would go, for a non-profit's fish habitat restoration. I've also seen j-hooks and vanes installed so high that they impeded boats during lower flows. It's not good when your fish habitat project's poor construction really pisses off the fishermen and the regulators.<br /><br />4. If you have to change design or structure location during construction, tell the regulators. Call them up or email them, tell them what you need to do, and ask if it's okay to keep the contractor mobilized and supply as-builts after construction. If they say no, give them change drawings and ask for a permit modification, ASAP.<br /><br />5. Do your post-construction monitoring on time. Don't blow it off. If big things happen in the watershed that affect your project, tell them soon afterwards, and include it in your report.<br /><br />6. If you see that your structure(s) isn't/aren't working, tell them and propose a fix. Make sure your client is aware that sometimes, structures need tweaking and build that into your budget.<br /><br />Restoration is not an exact science. There's lots of schools of thought (and lots of arguments, too), and no single prescribed method of conducting restoration. If you're prepared to have an honest, humble dialogue with your regulators and give them the information they need to evaluate your project up-front and after construction, you'll likely have a very successful restoration business.coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com2tag:blogger.com,1999:blog-371888302852802442.post-63303783878886822832009-10-21T06:49:00.000-07:002009-10-21T06:56:43.210-07:00Fall's first snow...<span style="text-decoration: underline;"><span style="font-weight: bold;"><span style="font-family: times new roman;"><span style="font-weight: bold;"></span></span></span></span><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgFXURkLo_58r3bAmIRmtOD0tpW3RDFWvkXfldmt3hI1l_54V3UMDcNblbwfVmgo5F6fFEWPUMph01-C3w5YaupXoQb51Eouao6V_9atK_M4vZu6p2KDcTK9JviCBjNlAceehyTCwTJZ6w/s1600-h/PA210189.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgFXURkLo_58r3bAmIRmtOD0tpW3RDFWvkXfldmt3hI1l_54V3UMDcNblbwfVmgo5F6fFEWPUMph01-C3w5YaupXoQb51Eouao6V_9atK_M4vZu6p2KDcTK9JviCBjNlAceehyTCwTJZ6w/s200/PA210189.JPG" alt="" id="BLOGGER_PHOTO_ID_5395050819723495874" border="0" /></a><br />Snow at the Coconino household early this morning.coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com0tag:blogger.com,1999:blog-371888302852802442.post-35835068503519607662009-10-11T12:25:00.000-07:002009-10-11T12:43:36.370-07:00Back againI've taken about a month and a half off of posting and reading blogs, Twitter, etc. It actually took much longer to recover from the surgery than I had anticipated, but it was well worth it. I went back to work earlier than I should have, and thus ended up with a minor infection and more cramping/pain than was originally indicated. I spent many days on the couch with a book and pain killers. But I'm better now, and doggone it, the surgery worked. I still have a period, but happily pranced through field work on the worst day this last week. Astonishing. Still might need hrt, though, but I'm a little more disposed to it now. <br /><br />From what little I've read of other folks' blogs today, I can see I have some catching up to do. After reading Anne Jefferson's post on <a href="http://scienceblogs.com/highlyallochthonous/">Highly Allocthonou</a><a href="http://scienceblogs.com/highlyallochthonous/">s</a> , I see a post on stream classification might be needed. It would also be a good refresher for me - I have some stream stuff to wrap my head around in the near future, anyway. Also need to post something on the <a href="http://www.quiviracoalition.org/">Quivira Coalition's</a> annual conference and water symposium. Bill Zeedyk will have his new book on Induced Meandering available at the conference. I also need to see what my daughter's k-garten class is doing for Earth Sciences week, if anything, and maybe (cough) volunteer if I can break away from the work thing. I'm also peripherally participating in a "used tire bale as bank stabilization research project" and may have some thoughts about that in the next month or so. I also have a picture of a road cut near Mora, NM that needs posting. I have no geology references for that area, and so know little about it other that it looked like a fault through meta-seds with granitic intrusions. I don't work much in rx anymore, so I'll welcome any info to clue me in.

Specifically, dirt derived from the Permian Yeso and Sangre de Cristo formations (yes, it's a hint to where I live). It is pretty dark red, as seen in the photo below, and stains everything (if anyone has a suggestion to how to get it out of my five-year-old's clothes, I'm all ears). When dry, its clay content makes for great adobe trails and the dirt roads in the 'hood get well compacted and easy to drive. It would make a nice house from adobe bricks, but that's a large project for another lifetime.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlLo8mJav6c0KqL5LuZjF_dBe7fWdv-QOZ5INUHknNmf3MisXdM4srK9NIiJGIFvziOkPe05Eo6-IG47Q2GcQAgXfKQzE16IsT2DiFe_HlWEjWlpsOx_gx3ApRwb2AaGaO4jbaXqcTKp8/s1600-h/P7250029.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlLo8mJav6c0KqL5LuZjF_dBe7fWdv-QOZ5INUHknNmf3MisXdM4srK9NIiJGIFvziOkPe05Eo6-IG47Q2GcQAgXfKQzE16IsT2DiFe_HlWEjWlpsOx_gx3ApRwb2AaGaO4jbaXqcTKp8/s200/P7250029.JPG" alt="" id="BLOGGER_PHOTO_ID_5362407202841215522" border="0" /></a><br />The reason I bring this up is that geology is often the root of many incidents in my house, including this morning's. Because of the red dirt, and the current monsoon storms, I have a policy of no shoes in the house, in an exercise in futility to keep the red dirt off my new fake-wood flooring. [The kitchen floor tile and grout is actually the same color as the dirt, as I presciently knew the result of putting my mud puppy-child and significant other together in this environment, so close to the back door.]<br /><br />The occasional result of this policy is shown below. The outside shoes end up in the once black and white dog's mouth (now black and white with reddish-brown legs), with the following results.<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjo4GI1UOmB3KYYS4dA7QLAhvGLOfvCuACgJ7FDPfp0SpvrCxq8rICWWqgJP5K9sHmNRet0ETIeQfQt9aBXp5eoU4zx3Nb194anH6ehnAsp6c9IFF7aZX3z3O8sVn-R-pK4aYEBn3MDoHU/s1600-h/P7250031.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjo4GI1UOmB3KYYS4dA7QLAhvGLOfvCuACgJ7FDPfp0SpvrCxq8rICWWqgJP5K9sHmNRet0ETIeQfQt9aBXp5eoU4zx3Nb194anH6ehnAsp6c9IFF7aZX3z3O8sVn-R-pK4aYEBn3MDoHU/s200/P7250031.JPG" alt="" id="BLOGGER_PHOTO_ID_5362420999546617506" border="0" /></a><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikWHl9KuAdTg16XJQm-cVKI1Wbj9XVOyEekp_4QRROz5AepIatm6QzA8MpHGF_K4F7-dq6pXrxii7sfi3VmtFqryba_o0kBk0N__O52XXCdgxCu7CgvkZlgkk7fR1QxTIoWx8se1_BfkE/s1600-h/P7250030.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px; height: 150px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikWHl9KuAdTg16XJQm-cVKI1Wbj9XVOyEekp_4QRROz5AepIatm6QzA8MpHGF_K4F7-dq6pXrxii7sfi3VmtFqryba_o0kBk0N__O52XXCdgxCu7CgvkZlgkk7fR1QxTIoWx8se1_BfkE/s200/P7250030.JPG" alt="" id="BLOGGER_PHOTO_ID_5362420992140843010" border="0" /></a><br />As I was reading other blogs this morning, I looked out the dining room window, to note the black, white and red dog wandering by with a distinctly hot pink small Timberland sandal in her mouth.

Having reached my majority around the time when he was releasing his first solo albums and becoming "king of pop", I set about to educate my little one on the finer points of moonwalking while simultaneously reliving a wee bit of my late teens and early twenties through watching a series of his videos this last week.<br /><br />What struck me the most, at least in the outdoor videos, was the fact that most the scenery seemed to have been shot at his Santa Ynez valley ranch, Neverland. I know because one of my favorite hiking trails for about 9 years, in the 90s, was right next door, while I lived in Santa Barbara.<br /><br />I pretty vividly remember the last time I hiked that trail. It was spring, and a very good flower season. One of the peaks above, a triangular-shaped one whose name I forget (Zaca Peak?), was bright orange with eschscholzia california, California poppy. I came across one of the more beautiful groups of sisrynchium bellum (blue-eyed grass), I'd ever seen. It was a different blue, lighter than what I was used to seeing. The lupinus longifolius, bush lupine, was in full flower giving off that wonderful grape-juice scent. Down on the valley floor, the quercus lobata, or valley oaks were dripping with the green of their fresh spring leaves.<br /><br />Out of all the landscapes I've been, that driven by the Franciscan melange is my favorite, and the drive from Los Olivos up to Figueroa Mountain across the main ridgeline and over to the saddle between Figueroa Mountain and the San Rafael peaks best exemplifies that landscape to me. [Figueroa Mtn Road to Happy Cyn Road back to San Marcos Pass Road] From the serpentine Franciscan knockers, to the grassed shaley slopes, to the tall foothill pine forests at the top of the range, this landscape speaks to me like no other.<br /><br />The Franciscan melange in the San Rafaels along Figueroa Mtn Road is composed primarily of marine sediments, with serpentine Franciscan knockers showing up occasionally at the top of the mountain and along Happy Cyn Rd. The mix of differing sediments, each of which supports its own mini-ecosystem of flora, gives rise to a ruffled, patchwork landscape which is like no other I've seen, and is definitely one of my favorite.<br /><br />Though I don't have any photos (didn't have a digital camera back then), this one shows the triangular peak and really exemplifies the beauty of the area: <a href="http://www.flickr.com/photos/kimberzy/3394298928">Figueroa Mtn</a>, Flickr image courtesy of Kimberly Perkin.<br /><br />Though any fascination I might have once had with the "king of pop" is long gone, whenever I see one of his videos, I'll fondly look for images of the Santa Ynez Valley.coconinohttp://www.blogger.com/profile/12050625735753145388noreply@blogger.com5tag:blogger.com,1999:blog-371888302852802442.post-40844672497245828072009-06-16T21:10:00.001-07:002009-06-16T21:15:09.981-07:00Blogger comment window<div style="text-align: left;">Does anyone have a problem with Blogger only opening a dinky comment window with no means of expanding it, so that you can't post comments because you can't see all the word verification or most of your comment?

From Sun Valley erupting to Las Vegas sinking at least 200 feet into the vegas (did they really try to say it was sulphuric acid-eroded limestone in the alluvial valley?), it was a really horrid portrayal of natural events gone badder in much less than geologic time. If I had Emeril's smell-o-vision, rotten eggs would have been wafting from the set. <br /><br />I really loved (not) the rift fault propagating through the midsection of Canada and the U.S. in less than two days without any failed rift arms (would they have propagated and died in less than a day?). <br /><br />When my ex worked as a prof at an unnamed SoCal bastion of higher learning, he regularly got calls from "the industry" looking for quick answers to geologic questions (it helped that his last name is closer to the beginning in the alphabet - the industry geeks tend to go down the list). Some were interesting, but some were rather infantile. I remember him talking about some whining sod trying to find a good movie location and practically begging for a warm, but Iceland-like locale to shoot in a few weeks (it was the middle of winter-southern Idaho was right out). It has occurred to me, more than once, that I could probably have found some work as a geology "consultant" to the industry. I couldn't bring myself to even check into it, though, as I presume the writers and directors for movies like the one I saw tonight repeatedly shine on their consultants' pleadings for a dramatic geological activity that could actually happen in real time. <br /><br />At the end of the movie, everyone, from the president to the former head of the USGS and his now head of the USGS daughter, was crying crocodile tears. Myself, I can't imagine any geologist worth her/his salt not at least thinking: "Whoa, dude. That was so incredibly awesome!" as they watched a rift split the continent in half and fill up with ocean.
