The Continental Divide defines the southeastern corner of this landscape, marking the high boundary between Montana and Idaho. This high-altitude region is dominated by the Beaverhead National Forest and the Targhee National Forest, creating a protected corridor of peaks and valleys. The topography is anchored by prominent summits such as Elk Mtn, Deer Mtn, and Saddle Mtn, which overlook a network of alpine lakes and springs. To the west, the Red Rock Lakes National Wildlife Refuge encompasses the lower elevations near Elk Lake. The eponymous Hidden Lake Bench rises above Hidden Lake, while the north is defined by the Horn Mountains and Lost Mine Canyon. This 2017 survey details the complex hydrography of the area, including Antelope Creek and numerous numbered springs like 14S02E07CBAD01 Spring, reflecting the vital water sources in this high-country environment.
