1955 Map of Pacheco Pass

USGS Topo · Published 1957

About this map

The Diablo Range dominates this mid-1950s survey, defined by its complex network of seasonal springs, lakes, and high peaks along the boundary of Santa Clara and Merced counties. The Pacheco Pass Highway serves as the primary artery through the hills, passing through the actual Pacheco Pass before descending toward the San Luis Flat. This era captures the landscape before major water management projects altered the California interior, showing natural drainages like San Luis Creek and Cottonwood Creek in their original courses.
