1963 Map of Eldorado Peak

USGS Topo · Published 1965

About this map

Eldorado Peak and the high-altitude ice of the Mt Baker National Forest dominate this mid-century survey of the North Cascades. The map details a complex glacial system including the Inspiration Glacier, Eldorado Glacier, and McAllister Glacier, providing a benchmark for the extent of these ice fields in the early 1960s. Below the peaks, the landscape transitions into steep drainage basins for Newhalem Creek and McAllister Creek. Human activity is concentrated along the Hidden Lake Trail leading toward Hidden Lake Peaks and the site of the Crescent Mine located on the slopes above Marble Creek. The proximity of these alpine features like The Triad and Dorado Needle illustrates the challenging terrain that shaped early mining and recreational access in this part of Skagit County.
