Rich,
Where did you get the two that are labeled "Yuma type locality"? The top photo is a Sonoran fairly typical of the ones found in or near Yuma.

Maybe from the big intergrade zone over near Whitewater in So Cal but it still does not look quite like those gophers either. Many of the GBs at the extreme southern in of their range (in CA) have a lot of color and pattern contrast. Here's an example of one...
