2021 Map of North of Tecopa Pass

About this map

Emigrant Pass serves as a critical geographic transition point in this corner of the Mojave Desert, bridging the high ground of the Nopah Range between several distinct desert basins. The historic route of the Old Spanish Trl is clearly delineated as it traverses the landscape, cutting through Chicago Valley before crossing the pass into California Valley. This modern survey documents the persistent topography of these ancient travel corridors, where the primary infrastructure remains focused on traditional routes like Mesquite Valley Rd. The vast elevation changes between the peaks and the floor of the Pahrump Valley emphasize the environmental challenges faced by early travelers navigating this portion of Inyo County.
