2017 Map of Boulder Chain Lakes

About this map

White Cloud Peaks dominate this high-altitude landscape, where the Challis National Forest and Sawtooth National Forest converge. The topography is defined by a dense concentration of alpine hydrology, most notably the Boulder Chain Lakes system including Lodgepole Lake, Shelf Lake, and Hatchet Lake. These bodies of water occupy glacial cirques and basins carved between formidable summits like Castle Peak and Merriam Peak. The mapping of these remote basins, such as Chamberlain Basin and Four Lakes Basin, reveals a complex network of seasonal drainage and perennial snowfields. To the north, features like The Kettles and Little Redfish Lake illustrate the varied glacial landforms that characterize this wilderness area, providing a detailed record of the high-country drainage into Big Boulder Cr and other tributaries.
