Okanogan National Forest encompasses this high-altitude landscape along the Washington-British Columbia border, defined by the towering Tatoosh Buttes and the sprawling Ptarmigan Ridge. The drainage system is dominated by the Pasayten River and its numerous tributaries, including Bunker Hill Cr and Holdover Cr. This modern survey illustrates the convergence of remote wilderness and designated recreation, specifically highlighting the route of the Pacific NW National Scenic Trail as it traverses the northwestern slopes. Glacial features are prominent throughout the quadrangle, with Big Hidden Lake, White Lake, and Ptarmigan Lake tucked into the high basins. Notable landmarks such as Point Defiance and Sunset Meadow provide specific points of reference for those navigating the complex topography of the Tamarack Ridge area near the southern boundary.
