St Joe National Forest and Lolo National Forest converge at the jagged Idaho Montana state line, a high-altitude border defined by the watershed of the Bitterroot Range. This mid-1990s survey by the Forest Service captures the remote topography where Shoshone County, Idaho, meets Mineral County, Montana. The landscape is dominated by notable heights such as Berge Peak, Pegleg Mountain, and Flattop Mountain. Drainage patterns are clearly marked by the headwaters of Simmons Creek and Gold Creek, which carve deep valleys through the timbered slopes. The Avery Superior Rd and the 9th Standard Parallel North provide the primary navigational framework for this backcountry area. High-elevation features like Moore Lake and Summit Springs offer specific points of interest for those studying the hydrology and natural landmarks of this interstate boundary region.
