Mojave National Preserve is a protected area located within the Mojave Desert in southeastern California and southern Nevada, managed by the National Park Service and established to conserve desert landscapes and cultural resources. The preserve encompasses diverse landforms, historic transportation corridors, and military-adjacent lands, intersecting with Interstate 15, Transcontinental Railroad, and the broader American Southwest transportation and settlement history. It attracts visitors for dunes, cinder cones, and Joshua tree stands while overlapping ecological regions recognized by the U.S. Fish and Wildlife Service and state agencies.
Geography and Environment
The preserve lies between Barstow, California, Las Vegas, Nevada, and Joshua Tree National Park, spanning portions of San Bernardino County, California and Clark County, Nevada and bordering federal lands managed by the Bureau of Land Management and the Fort Irwin National Training Center. Elevations range from the dry Owens-like basins near Kelso Dunes to peaks such as Clark Mountain (California) and Mid Hills, creating environmental gradients referenced in studies by the United States Geological Survey and the Desert Research Institute. Drainage networks connect to palaeo-lake systems recognized in publications from the California Department of Fish and Wildlife and the Nevada Division of Wildlife, while historical travel routes such as the Old Spanish Trail and the Mojave Road traverse the landscape.
History and Establishment
Human presence within the preserve includes prehistoric occupation by Chemehuevi and Mojave people who left petroglyphs and trade routes linked to the Colorado River and inland networks cited in studies by Smithsonian Institution archaeologists. During the 19th century the region saw traffic on the Old Spanish Trail, Mormon Road, and Lincoln Highway corridors, and later infrastructure projects including the Santa Fe Railway and Union Pacific Railroad that influenced mining and settlement patterns. Twentieth-century developments featured Route 66-era commerce, World War II training in nearby ranges, Civilian Conservation Corps activity, and Cold War military expansions associated with Nellis Air Force Base and Fort Irwin. Conservation advocacy by organizations such as the Sierra Club, Desert Protective Council, and representatives in the United States Congress culminated in the 1994 federal designation authored in legislative material from the United States House of Representatives and the United States Senate.
Geology and Natural Features
Geologic formations include Miocene and Pleistocene volcanic fields, basaltic cinder cones like those in the Cinder Cones (Mojave), and alluvial fans that record tectonic activity from the Garlock Fault and San Andreas Fault systems studied by the United States Geological Survey. The preserve contains extensive aeolian deposits exemplified by the Kelso Dunes, gypsum playas, and relict fluvial terraces tied to paleo-hydrology documented by the National Oceanic and Atmospheric Administration and paleoclimatologists at University of California, Riverside. Landforms host archaeological deposits comparable to sites curated by the Los Angeles County Museum of Natural History and specimen collections in the Smithsonian Institution National Museum of Natural History.
Flora and Fauna
Vegetation zones include iconic Joshua tree stands (Yucca brevifolia) associated with associations documented by the California Native Plant Society and remnant stands of creosote bush and mesquite scrub similar to communities surveyed by the Bureau of Land Management. Faunal assemblages feature desert specialists such as Mojave desert tortoise (Gopherus agassizii) listed by the U.S. Fish and Wildlife Service and mammalian species including bighorn sheep and kit fox that are subjects of research by University of Nevada, Las Vegas and California State University, Fullerton biologists. Avian migrations along flyways recognized by Audubon Society records bring raptors, owls, and passerines to habitats monitored by the National Audubon Society and state birding registries.
Recreation and Visitor Services
Visitors access the preserve via Interstate 15, historic Route 66 approaches, and local highways leading to trailheads, interpretive centers, and trail systems administered by the National Park Service and volunteer groups such as Friends of the Mojave National Preserve. Recreation opportunities include backcountry camping, hiking routes to Clark Mountain (California), off-road vehicle routes overseen by policies informed by the Federal Highway Administration, and interpretive exhibits at the historic Kelso Depot restored in partnership with the National Trust for Historic Preservation. Nearby urban centers like Barstow, California, Baker, California, and Las Vegas, Nevada provide gateway services, while academic field courses from University of California, Los Angeles and California State University, San Bernardino use preserve facilities for research.
Conservation and Management
Management combines federal policy from the National Park Service with interagency collaboration involving the Bureau of Land Management, U.S. Fish and Wildlife Service, and state natural resource departments to address invasive species, wildfire risk, and threatened species recovery plans such as those for the Mojave desert tortoise submitted to the Federal Register. Preservation of cultural resources follows protocols in the National Historic Preservation Act and partnerships with indigenous communities including the Chemehuevi and Mojave people for site stewardship. Research partnerships with institutions like the Desert Research Institute, University of California, Riverside, and the Smithsonian Institution support monitoring programs and adaptive management under climate-change scenarios projected by the Intergovernmental Panel on Climate Change.
