Large (approx 6 to 8 inch SVL) dark lizard with a prominent black collar. Missing 1/3 of tail. Variation visible on back. Seen through a birding scope, it was basking on a dead tree at about 15 feet off the ground.
Multiple specimens were observed basking on the rocks along a trail.
Do collared lizards have a second clear eyelid?
Not 100% sure where, but in the Gloss Mountains.
