The United States Congress designated the Riverside Mountains Wilderness (map
) in 1994 and it now has a total of 24,004 acres
All of this wilderness is located in California
and is managed by the Bureau of Land Management.
With an eastern boundary that runs roughly parallel to the Colorado River, Riverside Mountains Wilderness varies from gently sloping bajadas to a rugged interior with numerous peaks and a craggy skyline. Canyons in the interior emerge from the mountains to open into washes that divide the bajadas. Big Wash crosses the western section and provides easy foot access. The northern section includes artifacts from several old mining operations. Foxtail cactuses and California barrel cactuses, both sensitive plants, dot the landscape. A small herd of burro deer call this Wilderness home.
