The pilot took off in his Super Cub from a private airstrip in a wheel/ski-equipped airplane on a local area flight. He attempted to land on an ice-covered, frozen lake, and, due to the bare ice conditions, he elected to land in a wheel configuration instead of ski configuration.
During the landing roll, as the airplane slowed, the left tire broke through a layer of thin ice atop several inches of water, and the airplane veered left.
The pilot applied engine power in an attempt to correct the veer, but the plane ground-looped to the left, sustaining substantial damage to the empennage and fuselage.
The NTSB attributed the accident to the pilot’s selection of unsuitable terrain for an off-airport landing, which resulted in a ground-loop.
