About this map

Cascade Pass serves as the focal point of this high-elevation survey at the crest of the Washington Cascades, marking the divide between the Skagit and Chelan county lines. The landscape is defined by its dramatic verticality, where the North-Fork Cascade River and Middle Fork Cascade River drain steep basins beneath massive peaks. Glacial activity is prominent throughout the terrain, evidenced by the Sahale Glacier, Spider Glacier, and Middle Cascade Glacier, which cling to the high ridges of Ripsaw Ridge and peaks like Mt Formidable.

Access to this remote region is shown via the Cascade River Road, which terminates as it nears the Stephen Mather Wilderness. Trail networks such as the Cascade Pass Trl and Middle Fk Cascade Trl provide the primary means of traversing the high cols, including Cache Col and Johannesburg Col. Significant alpine water bodies like Doubtful Lake and Trapper Lake sit in high cirques, illustrating the hydrology of the North Cascades National Park at the start of the 2020s.
