1958 Map of Liebre Mountain

About this map

The San Andreas Rift Zone cuts a distinct path across this mountain landscape, marking the tectonic boundary near the northern edge of the Angeles National Forest. In the late 1950s, the historic Old Ridge Route served as a primary artery through these canyons, passing the small settlement of Sandberg and the U S Weather Bureau Sta. The map reveals a network of service points for mid-century travelers and forest workers, including the Halfway Inn, Tumble Inn, and the Quail Lake Fire Sta. Mining and ranching interests are scattered throughout the steep terrain, evidenced by the Gillette Mine and the Paradox Prospect near Redrock Mountain. Water management for the region is highlighted by the Reservoir Summit and several named springs, illustrating the infrastructure required to sustain remote camps like Bear Gulch Camp and private holdings such as the Pine Grove Ranch.
