Sidewinders can be found in desert regions of western Arizona, southern Nevada, Colorado, southeastern California, and in the southwestern regions from Utah southward down into Mexico. These snakes inhabit hot, dry, flat areas. They can be found in rocky regions below the elevation of 5,000 feet as well as in dry, sandy, washes and riverbeds. They are also found in areas where creosote bushes are in abundance.
Sidewinders are another reason one should use caution when in the desert. Be careful where you step, place your hands, and sit your butt! You never know what might be lurking in the shade of the next bush you pass.
