On May 10, 1933, a half-mile wide F4 tornado struck the small community of Beatty Swamps (also referred to as Bethsadia). The tornado destroyed every structure in the town and either killed or injured nearly every inhabitant, with 33 of the 35 deaths occurring in the area. Much of the area was swept clean of debris, a reaper-binder was thrown 500 yards (460 m), and cars were moved hundreds of feet.
