2004 Map of Mount Lyall

About this map

Pacific Crest National Scenic Trail traverses the high ridges of the North Cascades in this 2004 revision, marking a critical corridor through some of Washington's most protected alpine environments. The map documents the convergence of several major land designations, including North Cascades National Park, the Lake Chelan National Recreation Area, and the Glacier Peak Wilderness. Notable water features like the Stehekin River and the northern reach of Lake Chelan flow through the deep glacially-carved valleys, while high-altitude landmarks such as Mount Lyall, Tupshin Peak, and White Goat Mountain dominate the skyline. Hikers and researchers can trace the routes through Agnes Gorge or locate established campsites near Company Creek and Hiltgard Creek, illustrating the recreational infrastructure managed by the Forest Service at the start of the 21st century.
