The Twin Peaks Wilderness Area to the north and the Lone Peak Wilderness Area to the south are home to approximately 150 Rocky Mountain goats. Although native to North America, few survived at the time of Utah's settlement. The herd in this canyon, known as the Lone Peak population, resulted from an initial transplant by the Utah Division of Wildlife Resources from the state of Washington in 1967. Largely out of view above the timberline in the summer months, the goats are frequently seen nearby high on jagged rocks during the winter, usually in groups of fewer than ten. Rocky Mountain goats stand three to three and one-half feet at the shoulder and weigh from one hundred to three hundred pounds as adults. Males and females have off-white long fur, a definite beard, short smooth horns that curve slightly backward, and black hooves. They are part grazers and part browsers, feeding on moss, lichens, berries, shrubs, and trees near timberline, where these mountaineers also find protection from predators and the weather. Spongy padding on the underside of each hoof helps them cling to sheer surfaces, aiding their survival in freezing temperatures, howling winds, and hazardous terrain.
