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.
Lately, some really intriguing abstracts have crossed my desk. In my humble opinion, the abstract business in the geosciences seems loosely constrained as of late. This one, however, may be the best example of slipping through the cracks. Apparently it was printed by AGU in a thick abstract volume in 1991...will verify if I can find the time. Hilarious nonetheless.
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. 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.

This scene near the Sheephole Mountains deep in the Mohave near Amboy, CA is the best example of a 'pediment' that I have yet seen. The green swaths debouching from the mountain front are active fluvial systems loaded with creosote bushes. Presumably, the underlying fluvial deposits are only a few meters thick. The active washes are winding through low-lying, flat, or 'planated' swaths of granitic bedrock that barely protrude above the alluvium.
Note the conspicuous, ancient, and deeply furrowed fan remnant extending from the range front. Looks like a giant chicken foot. Also note the spectacular lighting on the dissected Pleistocene piedmont deposits flanking the range. Went to this site as part of a Bill Bull field class at the U of AZ back in the early 90s. Old.
