RCMP say the man fell in a steep, treed area on Thursday and suffered a head injury.
Staff Sgt. Steve LeClair says it appears the man and a woman he was with found themselves in steeper terrain that they were able to handle and he fell while trying to walk down the slope.
The young man was transferred to a hospital in Vancouver, but died Thursday night.
On Jan. 7, a 43-year-old American man also died while skiing in very steep terrain on the mountain.
LeClair says such tragedies are a reminder that hazards exist within and outside the ski area boundary.
