Bighorn sheep are named for the large, curved horns borne by the rams (males). Ewes (females) also have horns, but they are shorter with less curvature.^[14] They range in color from light brown to grayish or dark, chocolate brown, with a white rump and lining on the back of all four legs.

Bighorn sheep generally inhabit alpine meadows, grassy mountain slopes and foothill country near rugged, rocky cliffs and bluffs.
