The Mojave Desert System Index serves as the master reference page for the entire project. Its purpose is to let a reader see, on one page, how the Mojave landscape, corridors, nodes, and site-cores fit together. It acts as a structural guide rather than a narrative article.
The index begins with the regional framework.
The Mojave Desert occupies a broad interior region of the southwestern United States bounded by the Sierra Nevada to the west, the Transverse Ranges to the south, the Colorado River to the east, and the Great Basin to the north. Within this landscape, mountain uplifts, basin systems, river corridors, and transportation routes have shaped both the physical environment and the patterns of human settlement.
The following index organizes the Mojave Desert into its major structural components.
Primary Geographic Framework
These features define the physical structure of the Mojave Desert landscape.
Mountain systems
San Bernardino Mountains
San Gabriel Mountains
Tehachapi Mountains
Providence Mountains
Granite Mountains
Piute Range
Clark Mountain
Major basin systems
Victor Valley
Lake Manix basin
Soda Lake basin
Silver Lake basin
Cronese basin
Ivanpah Valley
Death Valley basin
These landforms control drainage, sediment movement, and ecological patterns across the region.
Major River and Drainage Systems
Water is the dominant organizing force in Mojave geography.
Mojave River
Amargosa River
Owens River (northern margin influence)
Colorado River
The Mojave River forms the largest internal drainage system of the desert, flowing from the San Bernardino Mountains toward the Soda Lake basin.
Transportation Corridors
Travel routes through the Mojave follow the natural pathways created by mountains, valleys, and water sources.
Cajon Pass corridor
Mojave River corridor
35th Parallel corridor (Needles–Barstow–Mojave)
Daggett–Las Vegas corridor
Tehachapi–Mojave corridor
These corridors guided Indigenous travel, wagon roads, railroads, Route 66, and modern highways.
Primary Nodes (Level 1)
These locations organize the major systems of the Mojave.
Cajon Pass
Barstow
Needles
Mojave
Tehachapi Pass
Mojave River
Afton Canyon
Soda Lake
Ivanpah Valley
Kelso Dunes
Providence Mountains
Granite Mountains
These nodes appear on the Mojave system map and anchor the regional structure.
Regional Zones
To simplify exploration, the Mojave can be divided into six geographic zones.
Cajon Gateway and Upper Mojave Zone
Mojave River Corridor Zone
Barstow Transportation Hub Zone
Kelso Basin and Providence Mountains Zone
Eastern Mojave Springs and Mojave Road Zone
Colorado River Gateway Zone
Each zone contains its own cluster of site-cores and landscape features.
Top Site-Core Locations
These locations represent the most important interpretive anchors across the Mojave Desert.
Cajon Summit
Mormon Rocks
Barstow Yard
Casa del Desierto
Daggett Depot area
Camp Cady
Lane’s Mojave River Crossing
Afton Canyon Narrows
Soda Lake shore
Zzyzx
Kelso Depot
Kelso Dunes
Hole-in-the-Wall
Mitchell Caverns
Cima Dome
Teutonia Peak
Piute Springs
Fort Piute
Ludlow townsite
Needles depot (El Garces)
Each of these sites illustrates an important component of Mojave geography, geology, or transportation history.
System Navigation Structure
The Mojave Desert system can be explored using the following hierarchy.
Regional Zones
→ Corridor Systems
→ Primary Nodes
→ Site-Core Locations
This layered structure reflects how geography, hydrology, transportation, and settlement patterns developed across the Mojave Desert.
Significance
The Mojave Desert System Index provides a unified framework for understanding the region. By organizing landscapes, corridors, and historic sites within a single structure, the index allows readers to navigate the Mojave as an interconnected system rather than a collection of isolated places.
Benefit: 10/10.
This page becomes the master orientation guide for the entire Mojave project.
Hindrance: 2/10.
As the project grows, the index may need occasional updates to include additional nodes or site-cores, but its core structure should remain stable.
