Oreamnos americanus (Blainville)
Mountain goat
Description.—The mountain goat is of deer-size, with a stout body and a pronounced hump on the shoulders. The legs are short but the hoofs are large with large dewclaws. The neck is short and thick. The head is large and goatlike in appearance. The tail is tiny. The horns are slim, round and curve up and slightly backwards. They are hollow and are permanent structures, added to each year. The body is snow white, consisting of long, soft wool, which is longer and coarser on forelegs, neck and chin than on the body. Males have a distinct beard.
Mountain goats range from Washington and Idaho north to Alaska. Their nearest relatives are the Old-World antelopes, especially the alpine species of Europe and Asia.
