The desert landscape around Summit in Riverside County is defined by the drainage patterns of Salt Cr, which meanders across the arid terrain. This 2012 survey illustrates the modern path of The Bradshaw Trl and Bradshaw Rd, following a historic transportation corridor across the valley floor. The geography here is sparse, showing a network of ephemeral washes and service routes like Gas Line Rd that intersect near the settlement area. For those studying the evolution of desert routes or tracing 21st-century land use in the Colorado Desert, these layers provide a clear look at how human infrastructure navigates the natural hydrology of the region.
