1920 Map of Pacheco Pass

USGS Topo · Published 1920

About this map

Pacheco Pass serves as the primary gateway through the Diablo Range, connecting the coastal mountains to the broad San Joaquin Valley. This 1920 edition documents the early infrastructure of the region, including the Pacheco Pass Road winding through the hills and the industrial presence of the Shell Pumping Sta. The landscape is defined by its transition from high summits like Crevison Peak and Hagerman Peak down to the alluvial plains where early educational and community hubs like Occidental School, Cottonwood School, and the Cottonwood Church were established.
