2021 Map of Granite Pass

About this map

Granite Pass serves as the central geological transition between the massive Granite Mountains to the south and the Iron Mountains rising to the north. This high desert landscape, mapped in 2021, is defined by the broad expanse of the Cadiz Valley, where modern infrastructure follows ancient desert corridors. The primary artery of Rice Rd bisects the pass, tracing a route that has long connected these remote basins. Historical land use and utility development are evident in the path of Old Telephone Rd and the prominent Power Line Rd, highlighting the area's role as a vital infrastructure corridor across the eastern Mojave. The map detail highlights the stark topography where alluvial fans sweep down from the peaks toward the valley floor, crossing the administrative boundary between San Bernardino and Riverside counties.
