Oreamnos americanus. This large goat was surveying his domain from atop a rocky spire on the south side of Kachemak Bay. Mountain Goats inhabit the coastal regions in southeastern and south-central Alaska. Mountain Goat hooves have a hard exterior, with soft pads that allow them to climb steep, rocky terrain. Males and females are similar in appearance; but males are generally 40-50% larger and have slightly different horns. Adult female goats can weigh as much as 180 pounds; adult males are typically more than 300 pounds.
