Bannack, Montana was a great boomtown of the Old West. Founded in 1862 at the time gold was discovered in the area, it soon had a population of an estimated 10,000 and became the territorial capital. It also became noted for crime and vigilante activity.
But the gold petered out, people left and only a few hundred folks remained by 1872. By the 1940s, Bannack was a ghost town.
Today, it is a state park with more than 60 historical structures still standing. Bannack remains one of the West’s best preserved ghost towns.
