2017 Map of Forbidden Peak

About this map

North Cascades National Park and the Ross Lake National Recreation Area dominate this high-elevation survey of the Cascade Range. The landscape is defined by massive peaks and glacial features, centered on the formidable Forbidden Peak and the high ridges of Austera Peak and Klawatti Peak. These summits form a dramatic hydrological divide, feeding a network of alpine waterways including McAllister Cr, Fisher Cr, and the W Fork Thunder Cr. Below the peaks, Moraine Lake and Klawatti Lake sit within deep cirques, while features like Boston Basin and Tricouni Peak indicate the complex geological character of this protected wilderness. The absence of roads or permanent structures reflects the area's designation as a primitive backcountry zone, preserved for its topographical extremes and natural water systems.
