The NTSB's narrative final · quoted from the NTSB record

The non-instrument-rated pilot reported that the cloud ceiling and visibility began to deteriorate about 10 minutes after his departure on a 60-nautical-mile cross-country flight. He located the nearest airport, a snow-covered grass runway, and decided to land in lieu of continuing into the deteriorating weather conditions. There was a 65-foot-wide plowed path in the runway that was bordered by snowdrifts. During landing, the airplane struck a low-lying snow bank that was obscured by drifting snow. The airplane then veered left and struck a second snow bank causing substantial damage to the left wing. Prior to departure, the pilot obtained weather information for the planned route of flight using a commercial weather service. The lower cloud ceilings and visibilities were not forecast to begin until after the accident flight was planned to reach the intended destination.
