The newly designated Bitterroot mining district is located in the Bitterroot Mountains west of Hamilton and Darby. There is no known mining activity in the area.
According to a geological map of Ravalli County, intrusive granite from the Idaho batholith underlies most of the district. Glacial drift and Recent alluvium cover the valley of the Bitterroot River and the lower stretches of many of its tributaries (Sahinen 1957).
BOUNDARIES OF THE DISTRICT
The boundaries of this newly designated district are not discussed in current literature. It encompasses many east - flowing drainages coming from the Bitterroot Mountains within the Bitterrooot - Selway Wilderness Area: Blodgett, Sawtooth, Roaring Lion, Lost Horse, Rock, Tin Cup, Trapper, and Boulder creeks. Figure 1 shows the district as defined by the AMRB (1994).
