I went back out to above Sun Valley by myself. This is a Fence Lizard, better known as a Bluebelly. Bought a box of live crickets from a pet store. Turns out I was squeamish about reaching in the box to grab one cricket out of 30 or so. So I lost many on the ground. The lizards were right on the spot to eat them up. Next time I'm going to bring tweezers.
