Slate Peak and the surrounding high country of the North Cascades are documented here at the turn of the 21st century. This area, shared between the Mt Baker Snoqualmie National Forest and the Okanogan National Forest, highlights a landscape defined by its mining history and modern wilderness status. The presence of the Illinois Mine, Goat Mine, Whistler Mine, and Brown Bear Mine indicates a legacy of resource extraction that preceded the region's conservation.
