About Grant-Kohrs Ranch

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.
