DescriptionBannack State Park is a National Historic Landmark and 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 lost. Over 50 buildings line Main Street; their historic log and frame structures recall Montana's formative years.Home PageBannack State ParkContributor TypeState ParkCollectionBannack Journals, Letters, Documents
