Bannack State Park
Bannack is a ghost town in Beaverhead County, Montana, United States, located on Grasshopper Creek, approximately 11 miles (18 km) upstream from where Grasshopper Creek joins with the Beaverhead River south of Dillon.
Founded in 1862 and named after the local Bannock Indians, it was the site of a major gold discovery in 1862, and served as the capital of Montana Territory briefly in 1864, until the capital was moved to Virginia City. Bannack continued as a mining town, though with a dwindling population. The last residents left in the 1970s.
