neither is the upper part of Whistler/Blackcomb.
my dad and i were there several seasons ago in the spring and experienced the area's legendary (or is it notorious) quick change weather.
we were skiing mid-mountain and then went to the tip top (pretty sure it was the top of Whistler Mtn). it had been fairly clear mid-mountain and it appeared clear up top. however mid-way through the lift ride it got socked in, the wind kicked up and we pushed headlong into whiteout conditions.
me, i just got off the lift and pointed downhill (there were red trail markers). my poor dad got flustered. while i was just a few feet in front of him (i didn't completely ditch him!) he couldn't see anything and being quite a bit older wasn't cottoning to the total loss of visibility. thankfully somebody came down behind him and played guide (i think it was a patroller). we got back down to the mid-mountain area, where it had "mysteriously" cleared up again, in one piece. but neither of us hit the top again that day.
my dad is great to ski with, but since he's pushing beyond 75 he doesn't rip like he used to (he was on patrol at Sugar Bowl in the 1970s) and pretty much sticks to groomers and mellow weather these days. but back in the day he was Mr. Up A 6am-on-the-slopes-by-8:30-ski-through-last-chair mofo who wouldn't put up with any whiney crap from his bitchy kid (me).
