Near the center of downtown Three Forks, Montana, the Headwaters Heritage Museum occupies a modest, historic building that feels like a step back in time. Brick buildings and turn-of-the-century railroad architecture frame Main Street, where the restored Sacajawea Hotel and a statue honoring the famed guide hint at the town’s history. Patrick Finnegan, a dedicated local historian and member of the Three Forks Area Historical Society, helps preserve the stories and artifacts of the Missouri River Headwaters.

The Headwaters Heritage Museum, which started as the Three Valley State Bank, now holds a different kind of treasure, thousands of items, documents, and photos gathered by the Historical Society to preserve the region's culture. Long before Lewis and Clark, the Three Forks area was central to Indigenous peoples, serving as a confluence of rivers, hunting grounds, and a source for chert to make tools. The first lots of Three Forks were sold in 1908 by the Milwaukee Land Company, making it the key stop along their coast-to-coast railroad, bringing freight, passengers, and homesteaders into Montana.

The museum began in the 1970s, when the Three Forks Chapter of the Pioneer Society began collecting artifacts in a single room in the Sacajawea Hotel. By 1982, community fundraising secured the bank building, and the collection grew from 90 objects to more than 750. Today, with over 19,000 artifacts, including 13,000 online, the museum captures the layered history of the headwaters area.

Visitors can see treasures like a piano hauled upriver from St. Louis in 1865, a rare symbol of culture and refinement in the Old West. At that time, pianos were luxury items–heavy, fragile, and costly, equivalent to about $15,000 today–and transporting one upriver on a steamboat was no small feat. Many ended up in saloons, hotels, or the homes of wealthy settlers, each note carried a sense of civilization to the rough, and muddy streets of the western frontier.
