Its namesake, the Joshua Tree, dominates many areas of the landscape, especially in the higher western Mojave desert. It is a short, scraggly tree that grows and thrives in summer heat over 100F. There are many such days in the summertime.

Coyote at corner of Keys View Rd. and Park Blvd. This little guy looked very hungry and it was tempting not to feed him. I then went on my way to Keys View, returning to the same corner about 2 hours later.
The little guy was in the exact location with a different car pulled over right where I had been. Apparently, this is his corner and he works the people very well.
