About this map

Okanogan National Forest encompasses this high-elevation landscape in the North Cascades, defined by a complex network of alpine peaks and glacial drainages. Significant summits including Mount Lago, Ptarmigan Peak, and Osceola Peak form the high ground, while the Middle Fork Pasayten River and Eureka Creek carve through the deep valleys below. The map identifies several remote water bodies, such as Ferguson Lake and Lease Lake, which are characteristic of the high-country tarns found throughout this protected wilderness.

Mountain travel is oriented around historical high-country routes, with Shellrock Pass and Butte Pass providing passage between the steep ridges of Blackcap Mtn and Mtn Carru. The drainage patterns of Monument Cr and Robinson Creek further illustrate the primitive topography. This 2017 survey details the area's relief and hydrology, serving as a contemporary record of the terrain within the forest boundaries and townships like t39n r18e.
