About this map

Pacheco Pass serves as the central focal point of this 2012 survey, marking the vital transit corridor between the Santa Clara Valley and the Central Valley. The landscape is dominated by the expansive San Luis Reservoir, where the shoreline is defined by Cottonwood Bay and Tunnel Island. Public access to these waters is highlighted by the Whistler Point Area Campground and the Coyote Springs Area Campground.

Away from the water, the topography rises sharply into summits such as Hagerman Peak and Spikes Peak. This region is dotted with numerous small water sources and family-named landmarks like Frenchs Flat and Whisky Flat. The intricate drainage network is traced through named springs and creeks, including Soda Gulch, San Luis Cr, and curiously named features like Pigs Bath Tub, offering a detailed look at the hydrology of these coastal mountains before further modern development.
