The Lone Peak Wilderness is a 30,088-acre (121.76 km2) wilderness area located within the Uinta and the Wasatch-Cache National Forests in the U.S. state of Utah. The Lone Peak Wilderness was established in 1978 as part of the Endangered American Wilderness Act and was the only designated wilderness area in Utah until the enactment of the Utah Wilderness Act of 1984. Situated in the central Wasatch range on the Wasatch-Cache and Uinta National Forests, this wilderness is generally bounded on the north by Little Cottonwood Canyon, on the South by American Fork Canyon, on the west by the Salt Lake and Utah Valleys, and on the east by Twin Peaks. Timpanogos Cave National Monument is adjacent to the south boundary of the Wilderness.
