We camped at the Gunlock State Park, where a Utah DWR herpetologist joined us for several hours, who appeared to know every scaly and slimy critter within a 10-mile radius.
A few highlights came when a Smith’s Black headed snake was discovered beneath a cow paddy, about the size of a large worm. No one thought it possible to find such a tiny, shy being, unless you’re flipping cow poo! Other popular reptiles were the small, delicate banded gecko and the diminutive, invasive Pacific tree frog.

Saturday was spent in Snow Canyon State Park where we were entertained by Cheyenne, a young SUU student naturalist, who kept us riveted with stories on some of the more iconic herp residents. She was emphatic on how to keep the reptiles safe from park visitors and ravens. “If a tortoise is crossing the road, please help it to the other side in the same direction it’s headed. Otherwise, never pick them up for they may release stored water, which could mean their death from dehydration. She also cautioned us on leaving the trail, for the desert tortoise spends much of it’s life in its labyrinth of burros. “Your footstep could cause a collapse, entombing the animal.”

Next, Cheyenne pulled a fully mounted Gila monster from her magical tub. Oohs and ahhs were audible, the penultimate reptile. She enthralled them with its life history, spending up to 95% of its life underground, often in tortoise burrows, emerging during the spring months for mating and feeding. It may eat 1/3 of its weight in one meal, consisting of bird, tortoise, and snake eggs and young, young mammals, carrion, and whoever else smells delicious and small enough to fit in its ravenous maw. Many of the calories are stored in its tail, which nourishes the animal for much of the year. Amazingly, Gila monster venom is used for diabetes and obesity treatment. Asked if she had seen a Gila monster. “No, but it’s at the top of my list!” she said.

Following a Cheyenne led hike, we continued the herp search beyond the park boundary. A tortoise discovery brought considerable excitement and photos, a rare siting! But that was overshadowed a half hour later when a Gila monster decided to present itself to myself. I began shouting “monster” hoping to rein in the dispersed crew. They came scrambling through the creosote bushes in disbelief. We immediately sent a text to Cheyenne with the coordinates, hoping she would see her first Monster in the wild! Never have I witnessed more excitement in my students, a surreal moment. I must check with Cheyenne on her success in finding the monster!

The Gila monster is considered near threatened by the IUCN from habitat loss and pet trade. In Utah it is illegal to handle Gila monsters without a permit.
