PRELIMINARY: A snowboarder went missing in the afternoon on 12/23. His body was located and recovered six days later on 12/29. It appears he was walking on a cornice when it failed. That triggered an avalanche in unskiable terrain below. He was swept over a very large cliff and buried by avalanche debris in an area known as Beards Wheat Field. He was found by an avalanche search dog after avalanche hazard work with explosives was conducted by search personnel.
