About this map

Earthquake Valley and San Felipe Valley serve as the central corridors for this high desert landscape, defined by a complex web of historic routes and modern trails. The map preserves the alignment of the Stage Coach Trl and Wells Fargo Trl, tracing the path of 19th-century transit through Foot and Walker Pass. These historic thoroughfares are intersected by the Pacific Crest National Scenic Trail and the CA Riding & Hiking Trail, which wind through the foothills of Granite Mtn and Grapevine Mtn.

Evidence of local development is centered around the Desert Wings Sky Ranch Airport, while the presence of Sentence Cienaga highlights rare desert water sources in an otherwise arid terrain. From the southern expanse of Blair Valley to the northern reaches of Sentenac Canyon, the map documents a geography where historic overland routes and early aviation infrastructure meet the rugged crests of the San Diego backcountry.
