I've been asking a bunch of the older rippers up there about it, and names that have hit it include John Mason, Scott Gaffney, and a few no-name, still-drunk-from-the-night-before locals. One year the winds moved the snow up it so it was only about 50 feet from the top to bottom, another year they measured from the top to a dude's bombhole and it was 88 feet.
The cliff is also known as "Kong," btw. I heard Ian Borgesen was "definitely going to hit it this year," and I have also been waiting for the right conditions.
