1959 Map of Pacifico Mountain

USGS Topo · Published 1985

About this map

Pacifico Mountain dominates the high elevation of the Angeles National Forest in this 1959 survey, updated with revisions through 1974. The landscape is defined by the steep canyons of the San Gabriel Mountains, including Santiago Canyon and Aliso Canyon, where water sources like Aliso Spring and Fountainhead Spring supported early ranching and mining. The Southern Pacific railroad line cuts through Soledad Pass near the settlement of Vincent, marking a critical transportation corridor through the rugged terrain.
