...the mid-'80s, though I can't remember the exact year. '86 or '87?? I remember skiing through there a few days after it happened and being amazed and a teensy bit nervous. I never would have expected a snow avalanche off that slope.
That is what puzzled me everytime I drove by there. The slope isn't that steep to warrant such an event. Must have been one massive slab of snow on that slope that just "broke" causing all of that damage.
