"Dall Sheep," Wikipedia, the free encyclopedia. The Dall sheep is a species of sheep native to northwestern North America, ranging from white to slate brown in color and having curved yellowish brown horns.The sheep inhabit the subarctic mountain ranges of Alaska, the Yukon Territory, the Mackenzie Mountains in the western Northwest Territories, and central and northern British Columbia. Dall sheep are found in relatively dry country and try to stay in a special combination of open alpine ridges, meadows, and steep slopes with extremely rugged ground in the immediate vicinity, to allow escape from predators that cannot travel quickly through such terrain.
