2014 Map of Mount Lago

About this map

Okanogan National Forest dominates this high-altitude landscape, where the crests of the Cascade Range define a complex drainage system. Steep ridgelines connect prominent summits like Mount Lago and Ptarmigan Peak, while glacial basins hold isolated water bodies including Lake of the Woods and Ferguson Lake. The map reveals the intricate headwaters of the Middle Fork Pasayten River and Eureka Cr, illustrating how the terrain dictates the flow of water across these protected federal lands. Notable passes such as Shellrock Pass and Butte Pass provide the only navigable breaks in the wall of peaks that includes Mountain Carru and Osceola Peak. This topographic study provides a detailed record of the wilderness boundary between T38N and T39N, showing the high-country environment of northern Washington as it existed in the early 21st century.
