The story of Bearmouth

Montana's ghost towns span gold-rush gulches and the great homestead bust that emptied the Hi-Line.

Bearmouth is a former town located in Granite County, Montana, USA. It began as a trading post for the placer mining camps of Beartown, Garnet and Coloma, located in the hills north of Bearmouth in Granite County. A pioneer family named Lannen operated the gold exchange and ferry boat across the Clark Fork River. Bearmouth was not a mining camp, but rather a town that depended on the survival of other towns that were mining camps. During the late 19th century, enormously rich ores from Garnet were brought into Bearmouth to be shipped to smelters.
