Was at Northstar today with Trekchick and Squirreljam and DaveSSS description above apply's pretty well. Had to look for the piles of loose stuff or face a washout if technique wasn't near perfect (mine was far from perfect. Not a bad day though with great company and we did hit some fun stuff in the trees with 2 or 3 inches of fresh snow on it. Far from stellar, but still fun overall especially since I don't live in the area and it was my first day of the season.
I was at Northstar last weekend, before the rain/freeze, and was impressed by the number of people who passed me going sideways.
