Ovus dalli stonei

Enough about predators for now, although I'd also like to write about cougars and black bears sometime. Another North American mammal that Dee and Cal might see in this region is the Thinhorn Sheep (Ovus dalli), not to be confused with Bighorn Sheep (Ovus canadensis). As the name suggests, the horns of this species are thinner than those of the Bighorn Sheep. They also have a more open curl, which some consider more elegant. Two races of Thinhorn Sheep call British Columbia home. The white Dall's Sheep is found in the Yukon and in the extreme northwestern corner of B.C. The darker Stone's Sheep is more widespread, being found in much of the region the trikers are in now, especially at Muncho Lake.

Living as they do in some of the most remote wilderness in British Columbia, both Dall's and Stone's Sheep have not suffered seriously from the encroachment of human activities. There are healthy populations of both, and that is perhaps a solid lesson in the importance of maintaining large tracts of intact habitat.
