1963 Map of Cascade Pass

About this map

Diamond Mine and Midas sit high on the slopes above Morning Star Creek, evidence of the prospecting history in this alpine section of the North Cascades. This 1963 field survey documents a landscape of immense ice and rock, where the Quien Sabe Glacier and Boston Glacier dominate the high ridges near Boston Peak. The map captures the boundary between North Cascades National Park and the Glacier Peak Wilderness, tracing the divide between Skagit and Chelan counties along the crest of Sahale Arm and Ripsaw Ridge. Below the peaks, alpine basins such as Horseshoe Basin and Boston Basin feed the headwaters of the North Fork Cascade River and the Stehekin River. Notable high-altitude water bodies like Doubtful Lake and Trapper Lake are shown nestled among the summits of Sahale Mtn and Magic Mtn.
