About this map

The Skagit Range dominates this high-altitude landscape along the United States and Canada border in Whatcom County. This 2017 study illustrates a wilderness defined by its dramatic verticality, where the Pacific NW National Scenic Trail winds through deep valleys and over high passes. The map documents the overlap of the Mount Baker National Forest and the North Cascades National Park, tracing the rugged drainage patterns of Silesia Cr and the Chilliwack River.

Notable summits like Mount Sefrit and Granite Mtn provide fixed points for navigating this complex terrain. The elevation data reveals the importance of natural corridors such as Hannegan Pass and Mamie Pass for movement through the region. From the steep depths of Hells Gorge to the high waters of Pocket Lake, the topography underscores the role of the Cascades as a formidable natural barrier and a preserved corridor for modern recreation.
