The No Mans Land Historical Marker, located in Harper County, Oklahoma, near the junction of US-64 and N1680 Road, pays homage to an area with a unique history. Once claimed by Texas until 1850 when it was ceded to the U.S. government, this region became known as No Mans Land. The marker is situated within Beaver County, which has its own interesting past. Knowles, originally Sands City, started in 1906 with the incorporation of Frances and Allie Knowles. This area attracted outlaws, cowboys, and settlers alike, with Beaver City being the largest town at that time. By the Organic Act of 1890, Congress attached No Mans Land to the Oklahoma Territory, eventually becoming part of the state of Oklahoma. Today, the area is known for its rich history and distinctive landmarks like the No Mans Land Historical Marker.
