2012 Map of Silurian Valley

About this map

The Silurian Valley is a stark and dramatic corridor of the Mojave Desert, defined by the ancient drainage patterns of the Riggs Wash system. This 2012 survey illustrates the hydrological character of the region, where seasonal watercourses trace paths across the alluvial fans and basin floor. The geography here is marked by the distinct accumulation of sediments in the valley's center, a reflection of the area's arid environmental processes. For those studying the California desert, the map provides a precise layout of the sparse road network and natural landmarks that serve as the only navigational aids in this expansive, undeveloped terrain.
