Northwestern Oklahoma

The region consists of Cimarron, Texas, Beaver, Harper, Woods, Alfalfa, Grant, Kay, Ellis, Woodward, Major, Garfield, Noble, Dewey, Blaine, and Kingfisher counties.

The area is anchored economically by Enid, which also contains the region's largest commercial airport.

At the time, federal law, based on the Missouri Compromise, prohibited slavery in the region that would become the Oklahoma Panhandle.

The passage of the Organic Act in 1890 assigned No Man's Land to the new Oklahoma Territory.

Another mesa range, the Glass (or Gloss) Mountains, sits in the center of Northwest Oklahoma, just south of the Cimarron River along Highway 412.
