Cass County Historical Society Museum at 646 Main in Plattsmouth, Nebraska, tells the history of Cass County since 1854, the year the county was opened for settlement. Permanent displays depict various stages in the county's history and are supplemented by temporary exhibits which are changed periodically throughout the year. Visitors learn about the golden age of steamboating on the Missouri River, the pioneer experience, the arrival of the train, and the importance of farm production. A second part of the permanent display covers the age of the automobile, the telephone and radio, churches and religious life, schools, and entertainment. There is a Pioneer room, a Victorian Parlor, and a General Store. The Society also maintains the Joseph and Mary Cook Log Cabin (1868); a Burlington Northern Caboose (1913); a life-size replica of Lewis and Clark's Pirogue which sit at Second and Main in Plattsmouth; and a one-room schoolhouse - Rock Bluffs - which is located southeast of Plattsmouth.
