In the Rocky Mountains of North America, steep cliffs were carved by glaciers. A snow-white mountain goat skips confidently along these rocks. Mountain goats’ physical features help them survive in this rocky alpine environment. They have special hoofs that prevent them from slipping and long hair to protect them against the freezing cold weather. Their secret to surviving in the high mountains begins in the summer. In only 2 short months over the summer, young goats must prepare for the harsh winter when temperatures can drop to 40 degrees below zero. Following mountain goats over the four seasons, this program explores their secrets of survival in this severe mountain landscape.
