2023 Map of Ross Canyon

About this map

The Diamond Mountains dominate this high-altitude landscape within the Plumas National Forest, where the terrain transitions from steep canyons into the broad expanse of the Beyem Seyo Valley. This 2023 survey documents a remote watershed system including East Chance Creek and Rogers Creek, alongside several isolated water sources such as Oso Kum Spring and Om Chatim Springs. The presence of the Milford-Beckwourth road provides the primary corridor through this mountainous region, connecting the rugged peaks to lower elevations like Thompson Valley. The topography is defined by prominent summits including Mudum Peak and Delunga Peak, which overlook deep-cut drainage features like Siegfried Canyon and McClellan Canyon. This map serves as a contemporary record of the complex network of creeks and springs that sustain the forest's ecosystem and historical travel routes.
