The private certificated pilot reported that he was landing on runway 1L, which required a correction for a 7 knot left crosswind. The pilot stated that after touchdown, he inadvertently allowed the airplane to veer to the right, and off the right side of the runway. The airplane's main wheels subsequently struck a snow bank, and the airplane nosed over. The airplane sustained structural damage to the left wing, fuselage, and empennage. The pilot noted that there were no preaccident mechanical anomalies with the airplane.
