Yes. The map, that map. Holy crap did I get sidetracked by life. Nonetheless, I have put some serious time into this and it is nearly complete and ready for review. The topology is clean. The attribution is nearly clean, etc. The big change in the unit scheme is the separation of fluvial deposits / surfaces by reach or area...e.g., Sand Springs area, West Crater lava area, Hole in the Ground area, and Owyhee Breaks area. The idea is that most of the terraces in these reaches are related to local controls...lava dams and landslides...and thus don't correlate well in time or to process as would be the case on a 'normal' river. The idea is at least partly to mostly correct. One interesting thing is that there is a suite of boulder bars that are at consistent elevations above the river over long distances...I am headed out to the field to work on a different river for a while. Have left plenty of notes to pickup where I left off in 10 days or so...
Our research group is finally getting our big paper about the Owyhee River finished (I am getting close with the map as well). I am hoping to snag the cover of GSA Bulletin with one of these photos. Any thoughts on the best? I like them all, of course, and some are true favorites...so be kind if you want to chime in. Want to narrow the field to 3 photos.
Got through much of the labeling crap in ArcMap today. Really not that big of a deal. These images show one of my favorite spots. Note the second image has an underlay of high-resolution NAIP imagery. Did you know that you can stream this right into your desk-mapping session. Game-changer. Trust me. Takes a bit of the mystery out of the map...no?
These three maps show very nice progress in completing the map in the Jackson Hole / Rinehart Canyon reach of the Owyhee. They also portend some serious basemap issues. The first image is the slopeshaded lidar with 5 m contours derived from the lidar. The second is the DRG with the lidar beneath it. The third is the conventional depiction showing the geology on the DRG. The first is by far the most intersting and appealing, but lacks tons of information...some of which can be added easily, other...not so much.
Over the course of the last 4 years, I have been working on many geologic maps in many different locations. The map of the Owyhee River has been a special challenge. Complicated, remote, spectacular, etc. Now the funding stream has stopped. I have nearly finished the map. It has seen so many permutations (top image from December 2008; middle from June, 2009, bottom from today). The current draft example is not the most aesthetically pleasing version, but it is the most complete. Now, I need to figure out the best way to cram it into a 'conventional' publishable mode. However, the map, its design, its base data, and its compilation defy convention on several levels. Recently, I have gained many insights on severe problems with the conventional mode of map publication...they involve time, money, and anachronisitc expectations. Now, on to subverting all of that. Wish me luck.
Today I had the surprising chance to hand-deliver two samples from the lowest of the lower Bogus lava to Brent Turrin in person at this geochron lab at Rutgers. We had a great time discussing the vagaries of Ar40-39 dating, sample preparation, and how it would be possible to kill someone with a flashlight. It was awesome!

Through a remarkably tortuous process using Picasa, Lightroom, Geosetter, Google Earth, Picasa online, and Google Fusion tables, I finally got this to work. And, If I had just a little time, I could speak seven languages, I could walk on water, and I would also explain how this worked. Also, in spite of all of their wonderful contributions to geolocation, Google can suck it for never upgrading the Owyhee River area imagery. I have had sweet imagery since 2007.
A huge landslide that must have blocked the river (now fronts the
reservoir above Owyhee Dam). The vast array of huge boulders and
tilted blocks below the headscarp is mind-boggling.
