The United States Congress designated the Lone Peak Wilderness (map
) in 1978 and it now has a total of 30,632 acres
All of this wilderness is located in Utah
and is managed by the Forest Service.
The largest of a trio of wilderness areas just southeast of Salt Lake City, the Lone Peak Wilderness contains very rugged terrain with narrow canyons and high peaks. It is located on the Uinta- Wasatch-Cache National Forest and is managed by the Salt Lake and Pleasant Grove Ranger Districts. Among the highest peaks are the Little Matterhorn at 11,326 feet and Lone Peak at 11,253 feet, where snow often can remain until midsummer. Much of the higher elevation is alpine, with large, open cirque basins and exposed rocky ridges. The region is geologically complex. You'll see sedimentary, metamorphic, and igneous rock formations in dramatic relief, as well as colorful bands stretching for great distances across mountainsides. A few small lakes add to the scenic beauty of the area. Douglas fir, subalpine fir, and aspen grow in isolated patches on north-facing slopes. Dense mountain brush and grass dominates the lower altitudes. State Highway Route 92 follows the American Fork Canyon and with the short stretch of State Highway Route 144, it forms the southern-southeastern boundary of the wilderness and provides access to trailheads and campgrounds. State Highway Route 210, along Little Cottonwood Creek Canyon, which also provides access, forms the northern boundary and separates Lone Peak Wilderness from Twin Peaks Wilderness just to the north. Several of the trails are easy to follow, but many require advanced navigation and route finding skills. Many people from the Salt Lake City area visit this wilderness area all year long. There are about 6 system trails totaling approximately 14 miles in the Lone Peak Wilderness area on the Salt Lake Ranger District side and 8 system trails totaling approximately 32 miles on the Pleasant Grove Ranger District side.
