1999 Map of Cascade Pass

USGS Topo · Published 2002

About this map

Cascade Pass serves as a critical geographic junction on this late-twentieth-century survey, marking the high divide where the North Fork Cascade River and Stehekin River headwaters diverge. This high-altitude landscape is defined by its glacial activity, with prominent features like Boston Glacier, Davenport Glacier, and Sahale Glacier crowning the peaks. The presence of the Diamond Mine near Sahale Mountain and another Mine further east suggests a history of mineral exploration in these remote elevations, even as the area is protected within North Cascades National Park and the Glacier Peak Wilderness. Named alpine features such as Doubtful Lake, Kool-Aid Lake, and Mount Formidable emphasize the isolation and challenging environment that characterize the Skagit and Chelan county line at the turn of the millennium.
