The State of Wyoming has the image of a bucking horse and rider on the license plates. The same image is also used for the University of Wyoming. What is the horse's name?

The Bucking Horse and Rider (BH&R) is a registered trademark of the U.S. state of Wyoming. In 1936, Wyoming trademarked the image for use on the state's license plates. However, the state's usage of the logo is traced back to as early as 1918. Wyoming is popularly known as the "Cowboy State," in part because of the use of the bucking bronco as its symbol. The University of Wyoming at Laramie athletic teams are nicknamed the Cowboys and Cowgirls, both of which use the bucking horse and rider logo on their uniforms.

The iconic horse Steamboat came from the Tyrrell ranch near Chugwater, Wyoming, northwest of Cheyenne, and was given to Cheyenne Frontier Days by its former general chairman, Ace V. Tyrrell. Steamboat is buried on Frontier Park grounds near bucking chute #9, the only animal ever given the honor of being interred on park grounds. In 1975, Steamboat was inducted into the National Cowboy Hall of Fame in Oklahoma City, and in 1979, into the Pro Rodeo Hall of Fame in Colorado Springs.

There are rumors that the horse could be two other horses. The image is reportedly from photographs in The University of Wyoming archives of Steamboat with a rider in various rodeos in Wyoming. There are no known pictures of the other horses, only rumors.
