The HF Bar Ranch is located in Johnson County, Wyoming about 20 miles (32 km) northwest of Buffalo, Wyoming in the foothills of the Bighorn Mountains near Saddlestring, Wyoming. The ranch is a working cattle ranch comprising about 36 buildings, built between 1898 and 1921. The ranch is associated with Wyoming state senator and U.S. Congressman Frank O. Horton, who purchased it in 1911 with financial help from his investment banker brother-in-law and sister-in-law, Warren and Demia Gorrell. The Gorrells and their children spent summers in Wyoming, while the Hortons stayed year-round.
