About this map

Pasayten Wilderness and the Okanogan National Forest converge in this high-altitude landscape dominated by the peaks of the Cascade Range. The topography is defined by significant summits including Mt Lago, Monument Peak, and Robinson Peak, which serve as the primary hydrologic divides for the region's complex drainage network. Water travels through systems such as the Middle Fork Pasayten River and Eureka Creek, feeding alpine water bodies like Eureka Lake and Ferguson Lake.

Transportation through this high country is limited to a primitive network of historic paths, such as the Robinson Creek Trail and Shellrock Trail. These routes navigate difficult transitions at Shellrock Pass and Butte Pass, providing the only established access between the deep glacial valleys. The map reveals a wilderness area preserved from modern development, where the names of features like Ptarmigan Peak and Wildcat Mountain reflect the local wildlife and the character of this protected forest environment.
