Roger Mills County

Roger Mills County sits in western Oklahoma and covers flat to gently rolling grassland terrain. The Canadian River forms its northern boundary, while the Washita River cuts through the region, shaping the landscape.

The county was established in 1892 and named after Roger Q. Mills, a former Confederate officer who later served as a U.S. senator from Texas. The region experienced early impacts of western expansion and settlement by American pioneers.

The Washita Battlefield National Historic Site preserves the location where Lieutenant Colonel George Custer attacked a Cheyenne village in November 1868.

The county is best explored by car, as towns and attractions are spread out and public transportation is limited. It is wise to have plenty of fuel and drive carefully through rural areas.

During the 1970s, the county became part of the Panhandle-Hugoton Gas Field, which stands as the largest natural gas reserve in the United States.
