Hi Greg,
I uploaded a couple of pictures from last week. (How come nobody ever talks about Whitney withdrawal syndrome?)
Anyway, there was still a lot of snow back there. Guitar Lake is covered, so you're going to have a lot of snow to cross before you get to Trail Crest. I didn't get pictures of them, but the switchbacks up (as far as I could see) looked mostly clear. If the temp warms up, I'd bring snowshoes. If it stays cool and you're getting early starts, you shouldn't have any postholing probs (but then I'd use crampons for speed and stability). Good luck.
