La Madre Mountains Wilderness is a protected area in southern Nevada west of Las Vegas between the city and Mount Charleston. Encompassing 47,180 acres, it includes La Madre Mountain and several archaeological sites. One of its most notable cultural resources is the Brownstone Canyon Archaeological District. Jointly administered by the Humboldt-Toiyabe National Forest and the Bureau of Land Management, the wilderness is significant both for its desert-mountain setting and for preserved evidence of earlier human use.
