2013 Map of Boulder Chain Lakes

About this map

White Cloud Peaks dominate this high-elevation Idaho landscape, a region defined by dramatic vertical relief and an extensive system of alpine tarns. The map illustrates a complex glaciated topography where features like The Kettles and the Serrate Ridge stand as evidence of the area's geological history. Within the Challis National Forest and Sawtooth National Forest, the drainage patterns are clearly visible, with Big Boulder Creek and Boulder Chain Lakes Creek carving deep valleys between sharp summits like Castle Peak and Merriam Peak. The distribution of water is remarkably dense, ranging from the larger Little Redfish Lake to remote high-altitude basins such as Chamberlain Basin and isolated pools like Lonesome Lake. The map serves as a precise guide to the named ridges and basins that have long drawn explorers to these central Idaho highlands.
