I left Vermont last night after a rainy day at Stowe. In my mind they have a couple weeks left in the mountain, though Starr and Lookout were starting to look pretty bare. Mostly the steep stuff is on its last legs. The woods still had a pretty decent amount of snow in them but are starting to melt. I think they'll make April pretty easy at a descent number of trails, but don't have much hope of going far into April. Either way, I've always thought of "Spring Skiing" as a euphemism for "this sucks, winter is over." Stowe definitely got the best base I've seen this year. I haven't been to Smuggs, but they might be worth looking at.
Skied Killington Monday, it's getting bare there. I've skied Okemo a couple times with my sister, they haven't had a good base all season but worked with what they had. My house is up a descent sized hill between these two and we have no snow left. From the road I could see bare spots peeking through though at Okemo. I skied the woods at Okemo over the weekend, definitely a mistake for my new skis. Those have got to be gone by now. I think a couple runs with great base at these resorts (Superstar, Chief, Quantum Leap) might make it a little longer, but if this heat doesn't break I don't see them making April.
This is the most depressing ski season I have on record.
