Mount Ashland dominates this section of the Siskiyou Mountains, where the high-altitude terrain marks the state line at the Oregon and California border. This survey documents a landscape defined by industrial and recreational transit, with the Pacific Crest National Scenic Trail winding through the Rogue River National Forest and Klamath National Forest. In the southern reaches, the small settlements of Colestin and Cole sit near the headwaters of Cottonwood Cr, illustrating the long-standing importance of these mountain passes for movement between the Rogue and Shasta valleys. The map records several notable plateaus and drainage features, including Mudusa Flat, Virgin Flat, and the cascading Chocolate Falls. The network of forest development roads, such as the Mount Ashland Ski Rd, highlights the area's development for both timber management and winter sports.
