About this map

North Cascades National Park contains some of the most dramatic alpine terrain in the Pacific Northwest, as documented in this late-1980s provisional survey. The map is defined by the sharp spires of the Picket Range, where ice and rock dominate the landscape. Significant ice masses like Challenger Glacier and Terror Glacier flow from high-altitude basins, feeding a network of steep drainages including Luna Creek and Goodell Creek.

The presence of numerous high-elevation water bodies such as Azure Lake and Luna Lake highlights the glacial activity of the era. Prominent summits including Mt Challenger, Mt Fury, and Mt Terror stand as sentinels over a wilderness largely devoid of human structures, emphasizing the topographical complexity of the region's interior. Surveyed just before the turn of the decade, the map records the position of naming features like McMillan Spire and Inspiration Peak within this protected environment.
