The personal flight, operating under 14 CFR Part 91, departed a field site in the area and the destination was the gravel bar on which the airplane dragged its wing. No flight plan was filed and visual meteorological conditions prevailed. The certificated private pilot, the sole occupant, was not injured. The airplane was substantially damaged.
