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

The flight instructor flew the glider earlier in the day and experienced '...a lot of lift...' and expected similar conditions for the dual instructional flight. He and the student were released off tow, encountered lift, and climbed to 4,000 feet. There, the glider experienced almost constant sink, as indicated by the variometer, and an off airport landing to hilly terrain was required. The glider experienced a hard landing on ascending terrain. The flight instructor reported 13,481 hours of flight experience, 380 of which was in gliders.
