The wilderness area's focus are badlands of highly erodible mudstone/siltstone just like Badlands National Park in S. Dakota. I didn't want to rely on technology, but the barren terrain made using a GPS a necessity. At one point I decided that I would get "deliberately lost" and not concentrate on knowing where I was at every single moment. I would rather run around the hills and explore small gullies and simply concentrate on where was north and east. It would be pretty hard to get seriously lost since there were roads in those directions only a couple of miles away. We just watched "The Martian" the other day and the landscape certainly reminded me of being on another planet. The area is known for producing dinosaur fossils, so I kept my eyes open. There certainly was a lot of petrified wood all over the place. I also found some hydrologic oddities. As I said, the sediments are highly erodible. I walked up some gullies that were maybe 6' wide but with 15-20' sides. Slumps were common. In some places the gully was dammed, but the water simply flowed into the hillside and formed a little tunnel around the blockage. I thought that was pretty cool. Here are a few pics.
New Mexico or Mars?
A hoodoo! These were fairly common. A hard rock forms a cap which protects the soft sediments underneath. Soon erosion will catch up and the rock will fall.
These rocks much be rich in manganese to be so black
