Circle Montana named after a cattle ranch.
Major Seth Mabrey, a Confederate Army officer, came to the Redwater Valley about 1883, driving a heard of longhorns from Texas. As President of the Mabrey Cattle Co., he branded with a plain circle iron. From the brand, the operation became known as the Circle Ranch.
About 1903 the area needed a more reliable supply source. Local sheepman Peter Rorvik opened a store on the ranch. So began the town of Circle. In 1907 the surrounding lands were opened to homesteading and the area has been producing grain and livestock ever since.
