Lined snake (Tropidoclonion lineatum lineatum). Lined snakes were encountered most frequently near water and can usually be found in Vogel Canyon (northern section) except during the driest parts of summer.

JPG -- Superficial view of a lined snake

Lined snakes are superficially similar to several species of garter snakes, especially wandering garter snakes. Note the paired black ventral markings; wandering garter snakes occasionally showing dark ventral pigmentation, but it is never regular as in lined snakes. In addition, lined snakes are much smaller, with an adult maximum length of approximately 525 mm (usually much smaller).
