Jackson Sundown (1863 – December 18, 1923), born Waaya-Tonah-Toesits-Kahn (meaning Blanket of the Sun), was a Native American rodeo rider who has become a folk-hero for his mythic performance in the 1916 Pendleton Round-Up, largely popularized by Ken Kesey's novel The Last Go 'Round. A large gathering of Native Americans continues at the Pendleton Roundup in Pendleton, Oregon where a pow-wow is held during the Round-up in late September. Stories of Waaya-Tonah-Toesits-Kahn continue to fill the air at this event among the drumming, fry bread, gambling and rodeoing.
