About this map

North Cascades National Park contains some of the most dramatic glaciated terrain in the region, as shown in this 1960s field-checked topography. The sheet is defined by massive ice bodies including the Inspiration Glacier, Eldorado Glacier, and the Boston Glacier, which feed into steep drainages like Thunder Creek and McAllister Creek. This landscape represents a high-alpine wilderness where geologic forces remain visible in features like the Moraine Lake and the jagged Tepeh Towers.

Human activity is sparse but notable, primarily centered on the Skagit Queen Mine located near Skagit Queen Creek. This industrial footprint, alongside the Fisher Creek Trail, provides a glimpse into the early prospecting and exploration history of the high Cascades. The map also delineates the Indefinite Boundary of the Ross Lake National Recreation Area, marking a period of transition in federal land management and conservation in Washington.
