About this map

Wrightwood and its surrounding mountain terrain are meticulously detailed in this late-twentieth-century revision. The map highlights the intersection of geology and history along the San Andreas Rift Zone, which carves through Lone Pine Canyon. High-altitude landmarks like Telegraph Peak, Thunder Mountain, and the Devils Backbone dominate the southern landscape, while the lower elevations reveal a network of remote ranching outposts including Niles Ranch, Prudhon Ranch, and Sharpless Ranch.

Geographical and cultural markers are dense here, from the Pioneer Historic Marker at Stone House Crossing in the Cajon Basin to the Pacific Crest National Scenic Trail winding through the San Bernardino National Forest. The presence of a Shaft, several Prospect sites, and the Miners Bowl points to the area's prospecting legacy, while modern recreation is evident at the Mount Baldy Notch ski lifts and the camps at Manker Flat.
