2018 Map of Sombrero Peak

About this map

Sombrero Peak rises above the high desert floor of eastern San Diego County, surrounded by the granite outcrops of the Tierra Blanca Mountains and the In-Ko-Pah Mountains. This landscape is defined by its deep canyons and upland valleys, including Thing Valley and Lost Valley, which have historically served as vital corridors through the arid terrain. The presence of the Manzanita Cem near Canebrake suggests the enduring cultural footprint of the region's indigenous communities along the Tecate Divide. Seasonal watercourses like Canebrake Wash and the Tule Cr carve paths through Simmons Canyon and Rockhouse Canyon, reflecting a drainage system that dictates the placement of backcountry routes such as McCain Valley Rd and Old Mine Rd. The map detail traces the intersection of these ancient pathways with modern access roads, providing a view of the transition from the high desert valleys into the rugged mountain ranges.
