However, we can only hope that the spring is cooler than average, and that they can maintain a viable path down Broadway.
They can always cannibalize snow from the upper mountain or closed areas to build strips to the Main Lodge. It may turn out to be more work than they anticipate, but if you recall Memorial Weekend 2007
I believe they would do that work rather than renege on a previously announced closing date.
What's the skiing like by the end of June? Is it worth it?
You can ask Patrick, as he has come out from the East TWICE to do it. One of the virtues of Mammoth's late season is that terrain at both intermediate (with frequent grooming/salting to keep surface manageable) and expert (deepest snow is up high on the steeps, won't close prematurely like A-Basin does now with Pali) levels is still available to the end.
Only upper mountain pic from last June 13, likely similar to what late June will be (except very likely sunny) this year. Also you might want to look at the July reports from 2006:

My view is that such a trip should be viewed as a "mixed" vacation. It coincides with peak water levels in Yosemite, which is just an hour (Tuolumne Meadows) or two (valley floor) away. That peak water also makes for some great whitewater rafting, and the Tuolumne River is regarded as one of the best for that. Whatever you might want to do in a mountain resort in the summer (hike, mountain bike, rock climb, even golf
sorry, admin) it's all there along with the skiing. And often on the same day since skiing is finished by noon or 1PM.
As I will be leaving for Tahiti/NZ July 2 my last ski weekend is likely to be June 19-20.
