About this map

Onyx Peak stands as the central topographic focal point in this portion of the San Bernardino National Forest, where the high desert meets steep mountain ridges. The map reveals a landscape defined by seasonal water sources and early high-altitude industry, notably at Rose Mine and the isolated Bain Ranch. This terrain necessitated a complex network of paths, ranging from a standard Jeep Trail to the prominent Pacific Crest National Scenic Trail.

Evidence of small-scale settlement and recreation appears in the southern reaches, with Tayles Hidden Acres situated near the headwaters of Coon Creek. Unique local identifiers like Heartbreak Ridge, Broom Flat, and the Coon Creek Jumpoff illustrate how the environment's sharp relief dictated movement through the canyons. The eastern edge is dominated by deep drainages such as Pipes Canyon and Little Morongo Canyon, while numerous springs scattered across the slopes highlight the critical nature of water in this arid transition zone.
