Ground snake (Sonora semiannulata). Like many small fossorial species, ground snakes are near the surface when soil moisture is high (usually late spring and early fall). They are frequently found by turning rocks on south-facing slopes. These two individuals are from Cottonwood Canyon (southern section) and show the bright red background color more typical of snakes found here.

A large adult ground snake from bluffs just north of David Canyon Road (northern section). Note that the black bands do not cross the belly, a feature which easily distinguishes ground snakes from milk snakes. Ground snakes from this area have a much paler dorsal color (tan to pink), and some have only a longitudinal stripe of red.
