Replying to Summer skiing

im trying to ski this summer, at very least for a few weeks but possibly the entire summer if I can afford it/find work. right now i've been mainly looking at timberline, seeing as theyre open the longest but i was wondering if any other resorts stay open for a while into the summer. I finish school around May 5th and after that i'm free. if theres anything open from then until June id totally be on board with it. and ya I realize closure dates are based on annual snowfall but any best guesses for this years end date at your mountain would be really appreciated. any other information your willing to jot down for me i'll also be really stoked on.
