About this map

Picket Range crests dominate this portion of the North Cascades National Park, where high-elevation ice and sharp summits define the landscape. The massif of Mt Challenger serves as a central anchor, flanked by the Whatcom Glacier and Challenger Glacier. This 2023 survey documents the modern extent of these glacial systems and the surrounding drainage basins of Little Beaver Creek and Luna Creek.

Deep basins hold remote alpine waters such as Wiley Lake, Eiley Lake, and Azure Lake, while precarious crossings like Perfect Pass and Picket Pass connect the jagged ridges. The southern portion of the map is protected within the Stephen Mather Wilderness, featuring prominent landmarks like Inspiration Peak, Mt Degenhardt, and the formidable ice of Terror Glacier. The drainage network, including Goodell Creek and McMillan Creek, illustrates the complex hydrology of the Cascades' interior.
