The pilot was landing a tailwheel equipped airplane on a small snow covered airstrip. The surface of the snow was compacted by numerous snow machine tracks. After performing a low pass to assess the runway, the pilot proceeded to land. During the landing roll, the left tire broke through the crusty surface of the snow and sank. The airplane nosed over and received damage to the right wing, the right wing lift strut, the vertical stabilizer, and the propeller.
