1953 Map of Mt Challenger

About this map

The Picket Range dominates this mid-century survey of the North Cascades Park wilderness along the Canada United States border. High-altitude glaciology is a central focus, particularly the massive Challenger Glacier and Redoubt Glacier, which cling to the peaks of Mt Challenger and Mt Redoubt. The map documents a primitive network of high-country infrastructure, including remote backcountry refuges like the Little Chilliwack Shelter and Tapto Shelter, and trails crossing the continental divide at Whatcom Pass and Jasper Pass. This topography reveals the intricate drainage patterns of the Chilliwack River and Baker River systems, providing a window into the unpopulated interior of Whatcom County before modern conservation designations shifted the management of these peaks. The inclusion of features such as Phantom Peak and Crooked Thumb Peak highlights the complex vertical relief that long challenged early mountaineers and surveyors.
