All my identifications are subject to corrections--I do my best, but it's been 32 years since I took Herpetology. I based these on Sievert and Sievert's A Field Guide to Oklahoma's Amphibians and Reptiles.

Blanchard's Cricket Frog near the women's bathroom at the Doris Campground in the Wichita Mountains Wildlife Refuge.		Eastern Collared Lizard--the color form found in the Wichitas is spectacular! This was taken on May 9 near Quannah Parker Lake.
Eastern Collared Lizard	Red-eared Slider--two different ones. First photo taken on May 9, second on May 10.
Diamondback Rattlesnake--these were taken in Blaine County on May 11.
Southern Prairie Lizard (Sceloporus undulatus consobrinus) (on good authority)		Eastern Collared Lizard
More Eastern Collared Lizard--when you have a good photo op, why not use it? These were all taken on May 13 at the Refuge, near the Quannah Parker Lake and Dam parking area.		Eastern Fence Lizard in the same area.
Blanchard's Cricket Frog--taken at the women's bathroom at the Doris Campground.		I THINK this one is also a Blanchard's Cricket Frog.
Frogs gathered in the bathroom	They leave the light on for 'em.
This Diamondback Rattlesnake was apparently close to molting--the eyes are glazed. It also had a hulgy-bulgy area where it was apparently digesting someone. This was taken on May 14 at Fort Sill.
