Clarke Jackman

Clarke Jackman was born September 10, 1936, in Kansas City, Missouri. In 1954 Clarke enrolled in Colorado State University where he studied animal science and was on the rodeo team. After graduating with a bachelor’s degree in Animal Husbandry, Clarke moved his young family to Wyoming in 1958, where he managed the Mill Iron Ranch on Owl Creek in Hot Springs County. A few years later Clarke and wife JoAnn bought the Mill Iron Ranch where they ran about 400 head of Hereford cows along with 15 to 20 brood mares and raised five children. Every summer Clarke would hire a few “city” high school kids to show them a little of the cowboy life. He taught them the responsibilities of being a cowboy from breaking horses and trailing cows to farming and haying. Clarke was a steer roper for over 30 years. He qualified for the National Finals in 1975 ending up 15th in the world standings. He was well known for raising and training quality rope horses with seven different Mill Iron Ranch bred horses being used in the national steer roping finals.
