The glider pilot was flying north in a ridge lift about 400 feet above a plateau area where he had previously found good thermals. He started a turn towards the front of the ridge towards a valley and encountered a severe sink rate. He continued the turn and the sink rate increased between 1,500 to 3,000 feet per minute and the glider collided with trees. The pilot did not experienced a mechanical failure or malfunction of the airframe or flight control system.
Probable Cause: The pilot's inadvertent encounter with a downdraft while maneuvering in a ridge lift during a turn resulting in an in-flight collision with trees.
