Pituophis catenifer deserticola, commonly known by its standardized English name since the 1950s, the Great Basin gophersnake,[1][2][3] is a subspecies of nonvenomous colubrid snake ranging in parts of western United States and adjacent southwestern Canada.

[4][5] This snake can be found in the United States in Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming, and in Canada in British Columbia.

[6] The Great Basin gopher snake has dorsal spots that are dark brown or black, and they are connected to each other by very narrow lines that run along each side of the anterior part of the body.

On each side of the neck there usually is a dark longitudinal stripe that is surrounded by some lighter coloring, which eventually breaks up towards the posterior end of the snake and turns into dashes or small spots.

[8] The Great Basin gopher snake can be found throughout the western United States in grasslands, woodlands, deserts, coastal sage scrub, agriculture land, and riparian areas.
