2015 Map of Silurian Hills

About this map

Valjean serves as the primary named point of reference within this arid landscape in the mid-2010s, situated near the western edge of the quadrangle. The topography is dominated by the Silurian Hills, which rise above the surrounding Mojave Desert and the adjacent Valjean Valley. This terrain is characterized by complex alluvial wash patterns that drain from the hills, reflecting the hydrology of a high-desert environment. Transportation through this part of San Bernardino County is limited to a sparse network of county and local routes, including Silurian Lake Rd, Riggs Rd, and various designated county roads such as CR-20555 and CR-20554. The township and range lines, including t17n r8e and t18n r9e, provide a structured grid over this largely undeveloped section of the California desert.
