The Rocky Mountain bighorn sheep is usually found in rugged mountainous areas above the timberline only in the Rockies.
The male bighorn is 3 to 3-1/2 feet tall at the shoulder and weighs up to 300 lbs., while the female is slightly smaller. These large animals are known for their agility and perfect sense of balance. The bighorn sheep was named for its massive horns, which curve backward from the forehead, down, then forward. On the ram the horns can be as long as 50 inches.
