Where to find: Look up. Dall sheep live on mountainsides, walking on trails that would make any human nervous.
Look for Dall sheep at Denali National Park; along the Seward Highway at Windy Corner, Mile 106; and along the Glenn Highway at Sheep Mountain, Mile 107.
Tips: Dall sheep have curled horns and sleek legs, distinguishing them from the spiky horns and thick-haired legs of mountain goats.
A Dall ram's horns grow into a half circle after two or three years and into a full circle, or curl, in seven or eight years.
The nimble sheep grow to about 300 pounds for rams and 150 pound for ewes, feeding on a wide variety of plants. In the winter, they eat dried grass and sedge where the wind blows the snow off the ground.
