The partners Phillip Poindexter and William Orr moved their business to Beaverhead County. The P&O ranch recorded the first brand in Montana Territory, the square and compass.
History of the Museum
Thanks to some forward thinking women the museum now is a place that holds Dillon and Beaverhead County History for generations to come.
Dillon was founded in 1880 when the Utah and Norther Railroad came through the area. When it reached the ranch of Mr. Deacon he would not sell to the railroad.
On September 13, 1880, the Dillon townsite group assembled at Deacon's ranch. The deed for the property was recorded in the county courthouse in Bannack on September 16, 1880. The instant town of Dillon took shape.
