I'm here at Keystone this season and in response to below they now have a $30M upgrade into a new gondola that fits 8 people and gets to the summit in less than 12minutes (fast as) also has a mid station you can down load before the last hard pack snow (bottom of river run) that often gets stripped from beginner snowboarders sliding down it so that has been fixed now. They also have free bus services. As for being bitterly cold, of course this is the rocky mountains, that's why we are here.
