Ziebach County

South Dakota's north-central Ziebach County, established in 1911, is named for Frank M. Ziebach. The majority of the county lies within the boundaries of the Cheyenne River Sioux Reservation; small areas also lie within the Standing Rock Sioux Reservation. As the railroad penetrated the area, small towns sprang up. Dupree, the largest town in Ziebach County, was selected as the county seat. Founded in 1910, the town of Dupree celebrates its 100-year centennial with the publication of this history. The Ziebach County Historical Society is dedicated to preserving the history of the area's people, places, and events. A collection of nearly 200 photographs provides a glimpse into the past, along with modern development. Ziebach communities included Armstrong, Bridger, Chase, Cherry Creek, Dupree, Glad Valley, Iron Lightning, Redelm, Red Scaffold, Takini, and Thunder Butte.
