About this map

Mt Baker National Forest and Okanogan National Forest converge at the crest of the Cascades in this 1963 field survey. The high-altitude landscape is defined by massive formations like Ragged Ridge and peaks including Mt Arriva, Black Peak, and Corteo Peak. Glacial features are prominent throughout the quadrangle, notably the Lewis Glacier perched above Wing Lake and Lewis Lake.

Transport through this wilderness in the early 1960s was limited to significant footpaths like the Cascade Crest Trail and its alternate routes, which navigate difficult terrain through Easy Pass, Heather Pass, and Horsefly Pass. The map meticulously records the complex drainage systems feeding the West Fork Methow River and Fisher Creek, illustrating the remote topography along the Skagit, Okanogan, and Chelan county lines.
