2021 Map of Silurian Hills

USGS Topo · Published 2021

About this map

Valjean sits at the western edge of a landscape defined by the vast reach of the Mojave Desert. This terrain is characterized by the stark transition from the open Valjean Valley in the north to the uplifted topography of the Silurian Hills in the central and southern sections of the map. The network of desert roads, such as Co Rd 20555 and Silurian Lake Rd, suggests a region managed for accessibility across the arid basins. The southeastern corner drops into the Silurian Valley, providing a clear view of the complex drainages and alluvial fans that shape this part of San Bernardino County. Historically, these corridors like Riggs Rd have served as vital links through the high desert, connecting remote outposts and mapping the natural boundaries between these distinct valleys.
