1998 Map of Tolo Mountain

About this map

The Pacific Crest National Scenic Trail winds through high-altitude terrain along the divide between Douglas and Klamath counties, serving as a primary corridor through this protected landscape. This late-twentieth-century revision highlights a region defined by its volcanic geology and primitive water systems, where features like Windigo Pass and Tolo Mountain dominate the eastern ridgelines. The map shows the convergence of the Umpqua National Forest and Deschutes National Forest, with significant portions designated as the Mount Thielsen Wilderness and the Oregon Cascades Recreation Area. Hydrological patterns are marked by isolated basins including Windigo Lakes, Lake Lucile, and Maidu Lake, while the headwaters of the North Umpqua River and Tolo Creek drain the western slopes. A small Cinder Pit near Kelsay Point provides evidence of local material extraction amidst the otherwise preserved wilderness environment.
