About this map

Mt Sefrit and the Skagit Range dominate this high-elevation landscape within the Mount Baker Wilderness and North Cascades National Park. The map documents a complex network of glacial drainage systems, with the Silesia Creek watershed carving deep through the center, joined by the West Fork Silesia Creek and Middle Fork Silesia Creek.

Historically significant routes for wilderness access are meticulously detailed, including the Pacific Northwest National Scenic Trail crossing south of Mamie Pass and the Silesia Creek Trail. High mountain passes like Hannegan Pass and Skagway Pass serve as critical navigational waypoints between the peaks. The southeastern corner reveals the dramatic drop of Hells Gorge along the Chilliwack River, illustrating the extreme verticality of the Stephen Mather Wilderness.
