About this map

The Lyall Glacier clings to the high slopes above Rainy Lake, marking a landscape defined by sharp elevation changes and high-altitude water systems at the intersection of several major protected areas. This 1960s-era survey documents the convergence of North Cascades National Park, Wenatchee National Forest, and the Lake Chelan National Recreation Area. The map reveals a high-alpine wilderness accessible primarily by foot and pack animal, featuring an extensive network including the Bridge Creek Trail and McAlester Creek Trail.

Evidence of earlier human activity appears at the Prospect site on the upper reaches of Copper Creek, while the natural topography is anchored by prominent summits like Stiletto Peak and McAlester Mtn. Hydrological patterns are clear, with the North Fork Twisp River and South Fork Twisp River draining the eastern slopes below Twisp Pass. The mapping captures a specific moment in the management of these federal lands, emphasizing the transition between forest and recreation zones.
