Thank you--It's really a bland coloring, the B&W was the only choice I had. I like to think I'm learning some tricks to spice it up.
Knowing how to use a shovel and pick was a cheaper and smarter way for the desert miners to live. Lumber was very expensive and had to be hauled to the site. Living in the ground was cooler in the summer, warmer in the winter and presented a much more secure shelter. The wind across the broad, flat plains can be brutal. I've seen a couple "communities", built into the sand and clay. People lived in some of them as late as the 1970s.
This was taken during a 5 day geology/paleontology "death march" (drive) across the Mojave. We only spent about 10 minutes in this location as habitation sites were a lower priority than geological features, I try to snap as many shots as I can. Unfortunately, there was no time to make a complete photo record. I've seen inside these type of diggings before- Looks a lot like a hole, cubed.
