1953 Map of Mt Challenger

About this map

Mount Baker National Forest contains the heart of this mid-century survey along the international boundary between British Columbia and Washington. The map documents a landscape defined by glaciated peaks and the headwaters of the Chilliwack River and Baker River. A network of backcountry infrastructure is visible throughout the high country, including the Little Chilliwack Shelter, Indian Creek Shelter, and the U S Cabin situated near an abandoned Lookout. These sites, along with the Hannegan Pass Trail, provided essential refuge for early forest rangers and climbers navigating the terrain around Mt Challenger and the Challenger Glacier. The topographic data, compiled from aerial photography taken in the late 1940s and early 1950s, meticulously records features like Whatcom Pass and Beaver Pass, which served as critical transit points through the northern ranges before the modern era of wilderness management.
