California - Castle Mountains National Monument

State: California
Region: California Desert

In February 2016, President Obama designated the Sand to Snow, Castle Mountains and Mojave Trails National Monuments after hearing from thousands of supporters urging him to preserve these important lands. The designations come after nearly a decade of work by Senator Dianne Feinstein and countless others to ensure protections for these areas for recreation and important wildlife values.

The Castle Mountains National Monument designation added protections to 20,920 acres surrounded by the Mojave National Preserve. The Castle Mountains encompass native desert grasslands and wildlife habitat for Golden Eagles, desert bighorn sheep, mule deer, bobcats, mountain lions, golden eagles, Swainson’s hawks, desert tortoise, gila monsters, prairie falcons, Bendire’s thrashers, grey vireo, Townsend big-eared bats and California leaf-nosed bats. It contains some of the finest Joshua tree, pinon pine, and juniper forests in the California Desert and features stunning vistas of the rocky California and Nevada desert mountain ranges, including Nevada’s Spirit Mountain, which is revered by southwestern Native American tribes and listed on the National Register of Historic Places.
