About this map

Onyx Peak and Onyx Summit dominate the high-elevation terrain of the San Bernardino National Forest on this 2018 survey. The landscape is defined by its complex network of seasonal drainages and named canyons, including the significant Big Morongo Canyon and Little Morongo Canyon systems that carve through the San Bernardino Mountains. A major recreational artery, the Pacific Crest National Scenic Trail, snakes through the central and southern portions of the quadrangle, crossing high ridges and passing through Cienaga Seca.

Resource-minded researchers can trace the historic naming of remote features like Old Timer Canyon, Heartbreak Ridge, and Balky Horse Canyon, which reflect the early prospecting or ranching history of the region. The map also documents numerous water sources critical for survival in this arid environment, such as Yocum Spring, Broom Spring, and Pipes Spring, alongside established mountain routes like Burns Canyon Rd and Vista Rd.
