USGS Topo · Published 2024About this map
The Bitterroot Mountains straddle the Idaho-Montana border in this 2024 survey, highlighting the divide between Lolo National Forest and St Joe National Forest. This high-altitude landscape is characterized by a series of prominent summits including Illinois Peak, Gold Crown Peak, and Graves Peak, which define the rugged boundary of Shoshone and Mineral counties. The drainage patterns show waters flowing from sources like Saint Joe Lake and Missoula Lake into a complex network of gulches.
