There is a good reason why this is called a mountain goat: it lives in rocky terrain above the timberline up to 10,000 feet along the northwestern mountains and coasts of North America. This billy’s white coat is one of two protecting him in climates of minus 50° F with strong, sustained winds. Adult males can reach 225 pounds. Their black horns add growth rings during their 12 to 15 year lifespan. There are about 40,000 to 100,000 mountain goats climbing rocks in the wild. It is easier to see them at the Woodland Park Zoo in Seattle, Washington.
