The Powder River gathers itself in Northwest Wyoming and rumbles between gunpowder-dry riverbanks north into Yellowstone country. After crossing it in the late 1800s’ and putting a few celebratory pistol rounds through the roof of a saloon, a cowboy coined the phrase “Powder River, Let ‘er buck.” Wyoming troops used the refrain in the Spanish American War; they still do today. You’ll hear it at Wyoming fairs, rodeos, and football games. It’s uniquely Wyoming - just like our whiskey.
