Bannack State Park preserves Montana's first territorial capital, where the notorious Sheriff Henry Plummer allegedly led a double life during the 1860s Gold Rush. This remarkably well-preserved ghost town became the focus of Josh Gates' investigation into one of the Old West's greatest unsolved mysteries - the location of Plummer's stolen gold fortune. Today, visitors can walk the same dusty streets where outlaws and miners once clashed in this authentic piece of American frontier history.
Bannack State Park preserves Montana's first territorial capital, a ghost town founded in 1862 during the state's first major gold rush. Located on Grasshopper Creek approximately 11 miles upstream from its confluence with the Beaverhead River, the town now stands as a National Historic Landmark with over 50 preserved structures. Josh Gates investigated Bannack while searching for the legendary lost fortune of Henry Plummer, the town's notorious sheriff who allegedly led a secret gang of road agents while stealing gold from miners. The site offers visitors a remarkably intact window into Montana's Gold Rush era, where the line between law and lawlessness was famously blurred.

Bannack's history sits at the intersection of Montana's founding mythology and genuine historical controversy. Founded during Montana's first gold rush in 1862, the town rapidly grew into the territorial capital before being eclipsed by other mining camps. What makes Bannack exceptional in Old West history is the enduring mystery surrounding Sheriff Henry Plummer, whose story has been debated by historians for over 150 years.
Historians have long argued about whether Plummer was truly the criminal mastermind he was accused of being. According to the traditional account, Plummer served as Bannack's sheriff while secretly leading a gang of road agents who robbed and murdered miners along the territory's roads. Vigilantes hanged Plummer in 1864, convinced of his guilt. However, some modern historians have questioned whether Plummer was framed by the vigilantes themselves, who may have used allegations of criminality to justify their own extra-legal actions. The question of whether Plummer actually accumulated a stolen fortune remains tied to this larger historical debate.
Gates' investigation in "Plummer's Gold" explored the legend that Plummer successfully hid a cache of stolen gold before his execution. The episode examined various theories about where such a fortune might have been concealed in the rugged Montana landscape surrounding Bannack. Whether Plummer was guilty as accused or a victim of frontier justice, no verified cache of his alleged treasure has ever been recovered, leaving the mystery unsolved.
Today, Bannack's status as a well-preserved ghost town and National Historic Landmark makes it valuable for understanding Gold Rush-era Montana regardless of the treasure legend. The site's 50-plus structures provide archaeologists and historians with material evidence of daily life in a frontier mining camp, offering insights into the period that go beyond the sensational stories of sheriffs and vigilantes.
