1963 Map of Mt Lyall

USGS Topo · Published 1969

About this map

The Cascade Crest Trail traverses the high ridges of the Wenatchee National Forest in this 1960s study of Chelan County. This landscape is defined by its verticality, where the Stehekin River flows through the northeast corner, fed by numerous drainages like Agnes Creek and Company Creek. The map documents a glaciated environment, specifically marking the Company Glacier beneath the slopes of Mt Lyall and Lyall Ridge. Mountaineers and backcountry researchers will find detailed topography of prominent summits, including Tupshin Peak, White Goat Mountain, and Devore Peak. The presence of Battalion Lake and Lake Marie suggests the remote basins of the high Cascades, while Agnes Gorge highlights the erosive power of the region's waterways. This edition serves as a precise record of the alpine wilderness before later management changes in the North Cascades.
