About this map

Patton State Hospital anchors the valley floor in this mid-century survey, a period when the institutional grounds and surrounding citrus groves of Patton and Highland were the primary focus of development south of the mountains. The landscape transitions sharply from the suburban street grids of West Highlands to the steep slopes of the San Bernardino National Forest. Ascending the Rim of the World Drive, the map reveals established mountain resort communities like Lake Arrowhead, Skyforest, and Twin Peaks. This era shows the intricate network of fire roads and trails, such as the McKinley Truck Trail, necessary for managing the forested heights. The San Manuel Indian Reservation occupies a significant portion of the foothills, while the Atchison Topeka and Santa Fe Railway runs along the southern edge, illustrating the vital rail connection that supported the region's agricultural and logistical growth.
