About this map

North Cascades National Park and the Mount Baker National Forest converge at Cascade Pass, a significant high-altitude crossing that divides the watersheds of the N Fork Cascade River and the Stehekin River. This 2017 survey details the complex alpine topography of the Skagit and Chelan county line, where high basins and cirques contain isolated water bodies like Doubtful Lake and Trapper Lake.

The landscape is defined by massive massifs and ridges, including the sawtooth Ripsaw Ridge and the prominent Mt Formidable. Glacial features and high-altitude cols like Johannesburg Col and Cache Col provide critical context for the drainage patterns of the Middle Fork Cascade River and S Fork Cascade River. The southern portion of the map transitions into the Wenatchee National Forest, featuring the remote Yang Yang Lakes and the steep descent into Box Canyon.
