If Honeycomb is open and there's been a powder dump in the past week, then I think that Solitude has better tree skiing than Alta. They are both very nice places to ski, but if you haven't ever been to Alta, then you might want to just go there and check out the skiing off of Wildcat and Supreme. PCMR has some nice tree skiing as well, but it is lower angled than what you'll find at Alta and Solitude. The Canyons has some good tree skiing as well, but I still think that Alta and Solitude are generally better, but skiing the quakies can only be done on the PC side. If you go to whichever area is reporting the most snow, you'll have fun.
