The United States Congress designated the Cadiz Dunes Wilderness (map
) in 1994 and it now has a total of 19,935 acres
All of this wilderness is located in California
and is managed by the Bureau of Land Management.
The Cadiz Dunes Wilderness encompasses a major portion of the Cadiz Dune system and desert shrub lowlands just east of the dunes. These small dunes were formed by north winds pushing sands off the Cadiz Dry Lake. Due to the remote location these dunes, they had very little OHV use prior to their designation as wilderness. The pristine nature of the dunes and the beautiful spring display of unique dune plants have made the area a favorite for photographers. Borrego milkvetch occurs in the sand dunes and is listed by the California Native Plant Society as rare and endangered in California. Wildlife is typical for the Mojave Desert; including coyote, black-tailed jackrabbits, ground squirrels, kangaroo rats, quail, roadrunners, rattlesnakes, and several species of lizards.
Temperatures are fairly mild in the early spring, late fall, and winter--generally 30-80 F. Summer temperatures are extremely hot. Temperatures are commonly over 115 F and can get well over 120 F. Always carry water; desert springs are not reliable water sources.
