From Jonny Moseley on YouTube:

“The 1999 U.S. Open of Skiing from Vail, Colorado put on by Mike Jaquet and Micah Abrams of now defunct Freeze magazine. This was the second ever major ski slopestyle competition and featured switch take-offs and landings and off-axis moves that now look old school but were cutting edge back then. JP Auclair, JF Cusson, Vincent Dorian, Philou Poirier were the stars and a very, very young Tanner Hall is featured as well. The course was rough, but got the job done.”
