Uinta ground squirrels are a western Wyoming specialty of open meadows, sagebrush edges, and disturbed grassy ground. They are especially conspicuous in Jackson Hole and Grand Teton, including roadside flats and developed areas, and occur southward through suitable basins and foothills in the Green River drainage.

Their above-ground season is short. Adults emerge in spring, young appear by early summer, and many animals return underground by midsummer; that pattern explains the strong May–July record peak. A quiet colony later in the year may simply be dormant, and repeated reports from accessible park colonies can inflate apparent abundance.
