What is a Desert Tortoise
It only took me 10 years of living in the desert to finally see a Desert Tortoise in the wild!
The one below was photographed on Rainbow Rock Trail at the Valley of Fire State Park from a good distance away so we didn’t scare him.

Overview
DO NOT DISTURB THIS ANIMAL IF ENCOUNTERED IN THE WILD. A defense mechanism of this harmless reptile is to empty its bladder on whoever picks it up. The desert-dwelling tortoise cannot afford to lose this liquid.

What is a Desert Tortoise
I am an outdoor enthusiast who would rather be on a backcountry backpacking trip than a stroll on the beach (although I do love the beach!).
Living in Las Vegas has afforded me the opportunity to easily explore the Southwest region of the United States.
A nature lover, I am often found at the end of the pack taking photos and videos of the wildlife found on the trails. Colorful flowers, desert animals, and unusual geological rock formations are often the majority of my photos.
