I already answered your questions in the lift thread. But here goes again.
It's generally very good. The G zones and Northwoods are true north facing and will typically hold mid winter snow all year. Then the bowl wraps around 180 degrees with mostly east and some southern exposures. The Bowl almost always has the best snow in the valley, but it takes even the best skiers an hour to lap the G's.
If you haven't been the Highlands in a while, you'll really like the improvements. The new lifts are really nice, plus Mack and Ron have opened a bunch of new terrain.
I like the fact that I can ski full sun exposures top to bottom late in the day.
ASC used to close Highland's first because of overcapacity. Now they are closing it last on 4/22 and Aspen/Snowmass 4/15.
