Crotalus atrox
Either Western Diamondback rattlesnake (Crotalus atrox). Or Mojave Rattler (Crotalus scutulatus).
Desert.
I assume Western Rattler. But not 100% it's not Mojave or another type of diamondback.
If I could see the scales on the top of the head, I could tell you which snake it is. Please consider adding this to the new Snakes of the United States mission:
