Sonora Carver with the west’s first diving horse, trained in the United States and shown at the Calgary Exhibition and Stampede.

The horse dived about 50 feet into a tank of water about 10 feet deep and Miss Carver stayed on the horse during all of the jump. She lost her eyesight in 1931 when her horse landed badly, but by 1932 was again diving horses. She retired in 1942 and died in 2003 at the age of 99.
