About this map

Patton State Hospital and the surrounding community of Patton anchor the southern base of the mountains, where the urban grid of San Bernardino meets the rising terrain. This late-century update captures the suburban expansion around Highland and the Del Rosa area, showing the layout of San Gorgonio High Sch and Del Vallejo Jr High Sch alongside the tracks of the Atchison Topeka and Santa Fe RR.

The landscape transitions sharply into the San Bernardino National Forest, where high-altitude mountain resorts like Blue Jay, Skyforest, and Twin Peaks are clustered near Lake Arrowhead. The map documents the intricate network of fire management infrastructure, including the City Creek Firebreak and various truck trails, necessary for protecting these forested communities. Significant local geography is detailed through labels such as the San Manuel Indian Reservation and the prominent peak of Harrison Mtn.
