1959 Map of Pacifico Mountain

USGS Topo · Published 1975

About this map

Pacifico Mountain stands as a central topographic anchor in this high-altitude portion of the Angeles National Forest, where the landscape is defined by the steep descent into Santiago Canyon and Aliso Canyon. The 1959 data, with updates from 1974, captures a specialized mountain economy of isolated ranches and infrastructure. Long-standing local holdings like Niles Ranch, Montgomery Ranch, and Wagonwheel Ranch dot the canyons, while the presence of the Gold Queen Mine near Mill Creek Summit points to the area's mineral prospects.
