Sheep Stone

The Dall Sheep (originally Dall's Sheep, sometimes called Thinhorn Sheep), Ovis dalli, is a wild sheep of the mountainous regions of northwest North America, ranging from white to slate brown and having curved yellowish brown horns. There are two putative subspecies: the northern Dall Sheep proper (Ovis dalli dalli) which is almost pure white, and the more southern Stone Sheep (also spelled Stone's Sheep) (Ovis dalli stonei), which is a slaty brown with some white patches on the rump and inside the hind legs.
