ROCKY MOUNTAIN GOAT (Oreamnos americanus) Rocky Mountain Goats demand a very specialized habitat. These skillful climbers inhabit the craggy granite core of the Black Hills. Mountain goats are not native to the Black Hills. The population can be traced to six goats, a gift to Custer State Park by Canada in 1924, that escaped from their pens and found their home among the Black Hills granite peaks. There are now more than 200 mountain goats in the area. They have long, shaggy white coats that contrast sharply with their black horns, nose and hooves. The mountain goat's hooves are very soft to allow very steep climbing.
