The pilot reported that the cross-country flight was uneventful until the final approach portion of the landing to runway 27. She reported that the final approach was flown at the normal airspeed for the airplane. She said that the next thing she knew was that the airplane was on its nose and the left wing scraped the runway. The airplane then righted itself and skidded off the left side of the runway. The airplane incurred damage to the left wing spar. The pilot reported that the winds were from the west and that local pilots reported to her that winds from the west can create a swirl as it moves up the runway. The reported winds about the time of the accident were from 240 degrees at 11 knots, gusting to 16 knots.
