The majestic bighorn sheep is found in both the hottest deserts of the American Southwest and the coldest heights of the Rocky Mountains.
Males (rams) have large, thick, curving horns that can weigh up to 30 pounds. The horns of females (ewes) are less curved and thinner. Their diet consists of grass and clover during the warmer seasons and woody plants in colder weather.
Because of sensitivity to their environment, bighorn sheep are an excellent indicator of the quality of the land they inhabit.
