The Wyoming ground squirrel lives in grasslands and shrublands of the western United States. Its brown-gray fur is dappled, and it hibernates underground from late summer into spring at a Colorado study site.
Its fur is smoky brown-gray with cinnamon-buff dappling, and the underside of its tail is buff.
It centers its activity around underground burrows and eats grasses, forbs, shrubs, seeds, and insects. At Florissant, Colorado, squirrels enter their burrows in late July or early August and hibernate until March or April.
