The northwestern garter snake (Thamnophis ordinoides) is a species of snake in the family Colubridae. The species is endemic to North America.

Geographic range

In the United States, T. ordinoides is found in California, Oregon, and Washington; in Canada, it is found in British Columbia.[2]

Description

The northwestern garter snake is small, with adults averaging around 13–38 in (33–97 cm) in total length (including tail).[2] It is one of the most variable species of snakes in the world.[citation needed]
