MY FAVORITE PLACE! 
I am ENVIOUS of your Collared Lizard, I saw a nice male like yours, and he was posing on a really pretty rock, but as I brought up my lens, he shot off, it made me sick! 
Very nice shots, as you can probably tell already, to those that have been there, this has struck a chord. heheh
To the people that don't know, you should check this place out, there's all kinds of things to shoot there.
*DARK skies if you like night photography...
*Beautiful terrain...
*Elk...
*Bison and Longhorn Steer, like shown here)...
*Lots of many pointy antlered deer... 
*Lots of owls at night and other wildlife... Elks bugling, coyotes howling, *Canada geese squawking, etc...
*Lots of birds... (ducks and Canada geese too)
*Coyotes...
*Lots of Wild Turkeys...
*More Red Tarantulas than you can shake a stick at...
*Bald Eagles over around Elmer Thomas Lake and Lake Lawtonka...
*Great hiking too!
In less than two weeks, I'll be there camping for a week at Doris Campground, or as soon as the weather makes it to where it'll be good shooting weather.
Thanks for the boost, I was already excited about going back, but now you have made me salivate.
