About this map

Mt Baker and Glacier Peak dominate this 1962 Army Map Service compilation, which captures the rugged Northern Cascades before the full establishment of the modern national park system. The map documents the extensive wilderness regions of the Mt Baker National Forest, Chelan National Forest, and the Pasayten Wilderness Area. Concentrated human activity is visible primarily along the river corridors, with the Skagit River serving as a lifeline for timber and transport for settlements like Concrete and Marblemount.

Transportation networks of the early 1960s are clearly delineated, including the Great Northern RR and the North Cascade Highway. Industrial markers such as the Holden Mine near Lake Chelan and the Glacier Mine provide valuable data for researchers of Washington's mining history. The map also traces the complex drainage of the Sauk River and Suiattle River, showing the relationship between high alpine terrain and the lowland communities of Darrington and Rockport.
