Helena is a ghost town—killed, so they say, by one gunfight too many. In 1884, the son of the area's wealthiest rancher, Col. William Butler, was killed during a saloon shooting. Unable to find who fired the fatal shot, Butler vowed to kill the town that killed his son. He persuaded the railroad to bypass Helena by offering free land miles away. Helena lost its role as county seat, and its citizens drifted away.
Historic buildings include a farmhouse, the old post office and one of the four original jail cells. All are open the same hours as the museum.
