1963 Map of Mt Lyall

USGS Topo · Published 1987

About this map

The Pacific Crest National Scenic Trail winds through the high-elevation terrain of the North Cascades, crossing several prominent ridges that define the geography of the Chelan region. This 1963 survey, updated with 1980s aerial data, shows a landscape dominated by the high peaks of Mt Lyall, Tupshin Peak, and White Goat Mountain. The area is a confluence of major administrative boundaries, including the North Cascades National Park, Lake Chelan National Recreation Area, and the Glacier Peak Wilderness. Significant glacial activity is recorded at the Company Glacier, which feeds into a network of steep drainages such as Company Creek and Sable Creek. Water systems are central to the map, from the northern reach of Lake Chelan and the Stehekin River to isolated alpine features like Battalion Lake and Lake Marie tucked into the Fourth of July Basin.
