Just got back from 8 days there. The snow drought has been rough up there. Most of my favorite runs aren't open, but still had a lot of fun ripping around the mtn.
The parks are in pretty good shape most of the day. If you're going to ride cornice bowl, do it as early as possible. The groomies are fun to carve up the first 2-3 hours of the day. After about 11am expect to be riding on crud. There'll be icy wind blown patches, midday/afternoon slush, and random rocks kicked up on some runs.
Mammoth Brewing Company is great after riding. 10 free beer samples of really good brew, and it's totally worth picking up a growler or two. They're across from the village, but close at 6.
