About this map

Onyx Peak stands as the dominant high point in this high-altitude section of the San Bernardino National Forest during the mid-2010s. The landscape is defined by a series of steep drainages and ridges, where the Pacific Crest National Scenic Trail winds its way through the eastern San Bernardino Mountains. Significant topographic features like Heartbreak Ridge and the Three Sisters Peaks tower over a complex network of seasonal watercourses, including Pipes Wash and Cienaga Seca Cr.

The presence of isolated water sources such as Broom Spring, Missed Spring, and Pipes Spring suggests the vital importance of reliable water in this arid mountainous terrain. High passes like Onyx Summit provide natural transit points through the range, while named depressions such as Balky Horse Canyon and Old Timer Canyon hint at the area's human history and local lore. This map provides a detailed look at the interface between the high desert and mountain environments.
