The private certificated pilot was making a landing approach to a ridgeline that was oriented east/west, and was about 1,000 feet long and 30 to 100 feet wide. The pilot said he was landing toward the east. He described the wind as 10 to 15 knots from the southeast. As he approached the ground, the pilot said a burble of wind over the ridge lifted the right wing. The airplane collided with the ridge, and then nosed over. The airplane received damage to the wings, fuselage, and landing gear.
