Whitehorn Mtn has great terrain but poor lift access on the backside. A Poma and a slow boat triple, really!? A backside lap has two traverses. However, the tree skiing is extensive but not gladed as it is after all a National Park. The main south side runs are skied off promptly but the slack-country is almost never skied out. Deep pow is rare and the temps can be cold but come with blue sky days.
Mind bogglingly beautiful views all 'round you and 360 degree skiing.
I have skied +500days here and love this park as rocky as it can be. 2017/2018 has been an awesome season. If you like fast lifts and short boring runs go to Sunshine which, with the exception of DD, does not compare. Snow is a little better than LL though.
