Wilderness Profile


Just three miles off of Interstate 80, Castle Peak Potential Wilderness is among the most scenic areas in the Tahoe National Forest. Home to extraordinary old-growth red fir forests and the little Truckee River, Castle Peak provides clean drinking water to residents of Nevada County.

Mineral King Potential Wilderness

Size: Approximately 71,492 acres.

Managing agency: National Park Service, Sequoia Kings-Canyon National Parks.

Location: Just west of Sequoia National Park Wilderness near Three Rivers in Tulare County.

Description: This proposed wilderness is geologically unusual. Unlike the majority of the Sierra Nevada, which is made up of granitic rock formations, the Mineral King area is composed of metamorphic rock at high elevations. This has led to unique erosion patterns in the Kaweah watershed, allowing a variety of species to thrive here that are not normally found in the western Sierra. The metamorphic rock has also formed a karst topography full of springs, pits, sinkholes, and caves that are the finest in the Sierra Nevada. In California, only the Marble Mountain Wilderness contains karst features that are considered this extraordinary.

The Mineral King area contains a large portion of the Dennison-Garfield giant sequoia grove, the largest grove in the Sierra Nevada. It also includes five giant sequoia old-growth groves, as well as old-growth red and white fir stands.

The Mineral King area contains habitat for several listed species, including the peregrine falcon and golden trout. The area was formerly used by California condors and could be a re-introduction site in the future. The National Park Service is also considering this area for bighorn sheep re-introduction. Other species that make this their home include Pacific fisher, red fox, and wolverine.
