The Bitterroot Mountains define the high-altitude divide between Shoshone County, Idaho, and Mineral County, Montana, in this recent topographic survey. The landscape is dominated by the St. Joe National Forest and Lolo National Forest, where steep drainages like Sherlock Creek and Neversweat Creek feed into the protected Saint Joe Wild and Scenic River. A specific point of local history is found at the Heller Grave, situated near the headwaters of Blackburn Creek.
