Historic buildings surround fenced pasture, cattle being moved by cowboy on horseback toward viewer.

Wide open spaces, the hard-working cowboy, his spirited cow pony, and vast herds of cattle are among the strongest symbols of the American West. Once the headquarters of a 10 million acre cattle empire, Grant-Kohrs Ranch National Historic Site preserves these symbols and commemorates the role of cattlemen in American history.

The front portion of the ranch house was originally built by Canadian fur trader Johnny Grant in 1862.
