2021 Map of Pacheco Pass
USGS Topo · Published 2021About this map
Pacheco Pass serves as a critical geographic gateway through the Diablo Range, marking the high-altitude transition between the Santa Clara and Merced county lines. The landscape is defined by the expansive waters of the San Luis Reservoir, which reaches into the hills via Cottonwood Bay and surrounds Tunnel Island. This modern survey details a complex network of trails and water sources essential to the region's management, including Dinosaur Lake, Wolf Lake, and several remote springs like O'Connells Spring and Coyote Spring.
