This past weekend, some friends and I headed up to Whistler Blackcomb for a weekend of great skiing. We have a college buddy who's getting his PhD in Vancouver, so that's what motivated the trip. I've never skied in a place where the mountains were so huge. I've skied Jackson Hole and Mammoth, but apparently Whistler has a lot more elevation gain. This was proven when we skied the "Peak to Creek" run on the last day. We didn't do the 6.5 mile run because one guy was on a snowboard.
It snowed 8" on our first day and a few more on our last day. There was plenty of powder and lots of really steep runs. I highly recommend it - especially if you want to spend some money. It's not a cheap place to visit and it'll likely get more expensive since it's hosting the 2010 Winter Olympics. The good news is I got a 50% discount on lift tickets with my Winter Park pass. Whistler Blackcomb is owned by Intrawest - the same folks that own Winter Park and Steamboat.
