2015 Map of North of Tecopa Pass

About this map

The Nopah Range dominates this landscape in the eastern Mojave Desert, its steep ridgelines separating two distinct alluvial basins. To the west lies the broad, flat expanse of Chicago Valley, while to the southeast, the terrain transitions into the California Valley. This high-desert environment is traversed by a few key transit corridors, most notably where the primitive track of Mesquite Valley Rd winds along the eastern foothills. At the southern edge of the range, Emigrant Pass serves as a critical geographic notch, providing a natural route through the otherwise imposing mountain barrier. This 2015 USGS survey detail highlights the extreme isolation of these desert valleys, where the landscape is defined more by vertical relief and geological boundaries like t21n r8e than by human habitation.
