Range Description

This species occurs widely in the west of the United States, extending into northwestern Mexico. The range extends from southeastern Oregon, southwestern Idaho, and northern Utah south through eastern and southern California, Nevada, and western Arizona to northeastern Baja California and northwestern Sonora (Pianka 1991, Grismer 2002, St. John 2002, Stebbins 2003). Old records for northeastern Utah need verification (St. John 2002). Its elevational range extends from below sea level (desert sinks) to about 1,980 m (Stebbins 2003).
