1972 Map of Onyx Peak

USGS Topo · Published 1975

About this map

San Bernardino National Forest encompasses this high-elevation landscape, where 1970s land use reflects a mix of recreation, communication, and extractive history. Resource extraction is evident at the Rose Mine and Onyx Mine, while the Onyx Peak Radio Tower marks the summit as a modern infrastructure node. The transition from industrial to recreational use is highlighted by the presence of the Pacific Crest National Scenic Trail and the boundaries of Heart Bar State Park. Natural springs and cienagas, such as Cienaga Seca and Missed Spring, define the water sources in this arid environment. The map details a network of routes, from the H B S P Pack Trail to various jeep trails, connecting remote landmarks like Bain Ranch and the dramatic Coon Creek Jumpoff.
