Uinta chipmunk holds a solid 171-record showing in Wyoming, though its real range centers on the state’s higher conifer forest rather than the river-valley refuges its overlay locations list; this chipmunk favors mountain forest edges and rocky outcrops well above the Green and Yellowstone river bottoms.

Records build through early summer and peak at 52 in July, tracking peak above-ground foraging activity before a long winter hibernation. NatureServe ranks the species S4, Apparently Secure, in Wyoming.
