In 1950 Captain Jim Binkley, Sr. and his wife, Mary, launched a riverboat-excursion tourism business, which eventually grew from one 25-person boat to the current 900-passenger Discovery III sternwheeler. Three-hour tours with Riverboat Discovery visit the home and kennels of the late four-time Iditarod champion Susan Butcher and include a tour of a Chena Athabascan Indian village led by a Native Alaskan—as well as time to shop for souvenirs at the Steamboat Landing trading post.
