Bannack State Park is the site of Montana's first major gold discovery on July 28, 1862. This strike set off a massive gold rush that swelled Bannack's population to over 3,000 by 1863. As the value of gold steadily dwindled, Bannack's bustling population was slowly snuffed out. There are over 50 buildings that line Main Street with their historic log and frame structures that recall Montana's formative years.

A second website for the site can be found here.

The site offers exhibits, tours, educational programs, and occasional recreational and educational events (including living history events).
