The pilot landed a tundra tire and tail-wheel equipped airplane in a westerly direction and was slowing to begin taxiing to a parking area. At about that time, the airplane encountered a gust of wind from the right and went off the right side of the runway. The airplane received damage to the left wing tip, fuselage, and the left main gear attach point. The pilot estimated the wind was from the north at 16 gusting 22 knots.
