About this map

The hydro-electric infrastructure of the upper Skagit River dominates this 2014 survey, highlighting the industrial footprint within the North Cascades National Park. The map documents the complex operations at Newhalem and Diablo, where the Gorge Powerhouse and Newhalem Creek Powerhouse harness the dramatic elevation changes of the Cascades. Notable engineering landmarks include the Diablo Dam and the Gorge Creek Bridge, which span the narrow corridors of Diablo Canyon and Gorge Lake.

Beyond the river-driven settlements, the landscape transitions into high-alpine wilderness defined by permanent ice and jagged summits. Glacial features like Colonial Glacier and Neve Glacier sit below prominent peaks such as Snowfield Peak and Pyramid Peak. The inclusion of the Pyramid Lake Research Natural Area and numerous family-named landmarks like Paul Bunyans Stump and The Horseman provides a detailed look at how this mountain terrain is categorized for both conservation and navigation.
