2017 Map of Slate Peak

About this map

Mount Baker National Forest and Okanogan National Forest meet at a high-elevation boundary defined by the crest of the Cascades in this 2017 study. The landscape is dominated by significant peaks including Slate Peak and Haystack Mtn, linked by a network of high-altitude crossings such as Grasshopper Pass, Glacier Pass, and Harts Pass. This area is a critical junction for regional hydrology, where the headwaters of the W Fork Methow and Methow River begin their descent. A long section of the Pacific Crest National Scenic Trail winds through the center of the map, tracing the ridgelines past Tatie Peak and through Ninetynine Basin. The presence of multiple forest development roads, including Natl Forest Develop Road 374 Rd, highlights the managed access to these protected alpine environments at the border of Whatcom and Okanogan counties.
