Pacheco Pass serves as the focal point for this survey, marking the vital transit corridor through the Diablo Range on the boundary of Santa Clara and Merced counties. The eastern landscape is dominated by the sprawling San Luis Reservoir, with its underwater contours mapped by the California Department of Water Resources. This area, designated as the San Luis State Recreation Area, shows the early infrastructure of the reservoir system, including a Boat Ramp and the winding course of San Luis Creek.
