During a six-day expedition in September, 1997, Bart Bjorkman of Creston, British Columbia and John Chluski of Florida, both members of the Cambrian Foundation, successfully conducted two dives to a maximum depth of 360 feet fresh water (120 meters) on the 84-foot (26-meter) long sternwheeler S.S. City of Ainsworth. SueLynn Bjorkman, Al Cawte, Tim Gallagher, Ken Furman, Julie Kaye and Terrence Tysall provided the vital surface and in-water support that made this accomplishment possible.
