1958 Map of Whitaker Peak

USGS Topo · Published 1988

About this map

Frenchmans Flat and the rugged canyonlands of the Angeles National Forest anchor this 1958 survey, revised in the late 1980s to reflect major infrastructure changes. The map documents the dramatic intersection of transportation history and water management, showing the legendary Old Ridge Route winding through the terrain alongside the modern Golden State Highway. The southern portion of the map is dominated by the development of the State Water Project, featuring the Castaic Lake reservoir, the Castaic Powerplant, and Elderberry Forebay. These massive engineering feats contrast with older, localized landmarks like the Whitaker Peak Lookout and remote outposts such as Paradise Ranch and Martins. Along Piru Creek, recreational spots like the Frenchmans Flat Campground and Camp Cantu provide a record of mid-century forest use before modern expansions altered the local topography.
