Collared Lizard Swarm at Joshua Tree

Went to the usual place in JTree to see Collared Lizards and was rewarded by a greater variety than I've seen in some time. At least 8 individuals seen over a 2.5 hour hike. The special treat though was (what I think is) a big Yellow Back Spiny Lizard, which I hadn't seen in that area before: http:/...
