1991 Map of Tin Cup Lake

About this map

Vance Mountain anchors the high divide of the Bitterroot National Forest on this topographic study of the Idaho-Montana border. The landscape is defined by its drainage basins and high-elevation water bodies, notably Tin Cup Lake and the clustered Triple Lakes. These alpine waters feed a complex network of streams including Tin Cup Creek and White Cap Creek, which flow through the protected expanse of the Selway Bitterroot Wilderness. A primary Pack Trail serves as the essential corridor for movement through the backcountry, tracing the ridges and valleys between Idaho Co. and Ravalli Co. The map documents the region's wilderness character in the early 1990s, recording features like Patsy Ann Falls and White Cap Lakes before modern environmental shifts altered these high-country waterways.
