1955 Map of Pacheco Pass
USGS Topo · Published 1972About this map
Pacheco Pass serves as a critical mountain gateway through the Diablo Range, straddling the border between Santa Clara and Merced counties. This terrain is defined by the massive expansion of the San Luis Reservoir, whose blue waters and intricate shoreline are shown in detail alongside the San Luis State Recreation Area. The map reveals a complex hydrologic landscape of upland springs and small mountain lakes like Dinosaur Lake, Wolf Lake, and Nun Lake, which feed into steep drainages like Cottonwood Creek and San Luis Creek.
