Hysham is the county seat of Treasure County and is bordered just to the north by the Yellowstone River and to the south by beautiful rolling hills. Hysham has just about everything a visitor could need. This agricultural community spreads out in a panorama of green fields, pasture land and strips of grain.
At the beginning of the twentieth century, soon after the Montana territory earned its statehood in 1889, Hysham was a part of the great expanse of Custer Country. It was on what was then the Crow Indian Reservation. Cattle branded with the Flying E grazed near the Northern Pacific tracks where train men threw off supplies for Hysham. Charlie J. Hysham was associated with the Flying E Ranch, which ran thousands of cattle in an area between the Bighorn River on the west to Reservation Creek on the east, and from the Yellowstone River to the Wyoming line.
Treasure County has some outstanding historic sites. Manuel Lisa built the first building, a fur trading post in Montana near the mouth of the Bighorn River in 1807. Fort Cass was the first fort built by the American Fur Company on the Yellowstone, just three miles below the mouth of the Bighorn. Fort Pease was a stockade constructed in 1875, near the mouth of the Bighorn, as a defense against a party of Sioux Indians and also as a trading post. Remnants of Fort Pease still stand on the original site. Other fort locations remain a mystery.
Treasure County has a museum on Hysham's main street. Tales of Treasure County, a history of the people and events of the area is sold at the museum. Across from the museum is the historic Yucca Theater. A concrete sculpture of a white buffalo is an item of historic and artistic interest that stands as a sentinel in front of the theater.
