Ziebach County

Ziebach County spans 1,971 square miles of rolling grasslands and buttes, with the Cheyenne River flowing along its southern boundary and the Moreau River crossing the upper section.

The county was officially established in February 1911, incorporating sections of former Schnasse, Armstrong, and Sterling counties, marking the final administrative reorganization in South Dakota.

The territory encompasses sections of both the Cheyenne River Indian Reservation and Standing Rock Indian Reservation, representing substantial Native American communities and traditions.

County services operate from the administrative center in Dupree, with offices open Monday through Thursday from 7:30 AM to 5:00 PM and Friday from 7:30 AM to 11:30 AM.

Thunder Butte reaches an elevation of 2,733 feet, standing as the highest point in this county, which holds the distinction of being the last county alphabetically in the United States.
