1958 Map of Liebre Mountain

About this map

The Old Ridge Route snakes through the high country of the Angeles National Forest, marking a transition between the northern high desert and the steep drainage basins of the Transverse Ranges. In the late 1950s, this area remained a landscape of isolated waystations and high-altitude ranching, anchored by the settlement of Sandberg and the Rancho Corona del Valle. The presence of the U S Weather Bureau Sta and the Quail Lake Fire Sta underscores the importance of this ridge for monitoring the regional climate and fire risk above the San Andreas Rift Zone.
