1955 Map of Mount San Antonio

About this map

Mount San Antonio, also known as Old Baldy, towers over this high-altitude landscape where the San Gabriel Mountains meet the San Bernardino National Forest. In the mid-1950s, the area served as a significant recreational and industrial hub, featuring numerous mountain retreats such as Camp Maria Stella and Camp San Antonio, alongside working sites like the Native Son Mine and Big Horn Mine. The map captures the complex topography of San Antonio Ridge and Big Horn Ridge, carved by steep drainage systems like Vincent Gulch and Cattle Canyon. The presence of the Prairie Fork Guard Sta and the Angles Crest Highway indicates the established management of these wilderness areas, while lower-elevation features like Widman Ranch suggest the integration of private holdings within the surrounding forest land.
