Big deep at Shames

Boarder triggered Phazers side of V (slope opposite of Terminator) from the bottom of the V. Cut bottom of slope to have 4 m break of slope above on small open slope convexity. 20-30 cm's deep about 4 m wide. Upper bed surface was smooth. Snow filled up to my thighs. Soft enough to wiggle forward on board after it stopped. Heard 2nd hand of similar slide by another skier. Agian cutting/stopping at bottom of slope to have snow above break and run down at him.
