1941 Map of Arrowhead

About this map

The City of San Bernardino expands northward toward the San Bernardino Mountains in this pre-war survey, showcasing a landscape defined by the transition from urban grid to alluvial wash. Significant aviation history is recorded at the Shandin Hills Airport, situated near the base of the Shandin Hills and its Little Mtn Lookout. The intricate rail infrastructure of the Atchison Topeka and Santa Fe Railway and the Union Pacific lines dominates the western portion of the sheet, converging near settlements like Ono and Verdemont. The map reveals the early residential development of Muscoy and Arrowhead, while rural outposts such as Copia Ranch and the Del Rosa Ranger Sta mark the edge of the San Bernardino National Forest. This record captures the region's essential water management and transportation corridors, including the winding Rim of the World Drive as it begins its ascent into the mountains.
