1955 Map of Mount San Antonio

USGS Topo · Published 1958

About this map

The high peaks of the San Gabriel Mountains dominate this mid-century survey, centered on the formidable mass of Mount San Antonio, also identified as Old Baldy. The landscape is a network of steep ridges and deep canyons where early twentieth-century mining operations left their mark. Notable workings such as the Big Horn Mine near Vincent Gulch and the Stanley Miller Mine along the Iron Fork reflect the region's extraction history.
