Slate Peak and the high ridges of the Cascades dominate this 2023 survey of the northern Washington wilderness. The landscape is defined by its network of high-altitude corridors, most notably the Pacific Crest National Scenic Trail, which winds through dramatic features like Harts Pass, Grasshopper Pass, and Glacier Pass. This area marks a significant convergence of protected lands, spanning the Pasayten Wilderness, Mount Baker National Forest, and Okanogan National Forest.
