Estimate how long Mammoth will stay open this year.

their website has a detailed snowfall table that has their opening and closing dates. One day i looked at it for almost an hour. its SWEET.
 
late june im guessing, jul 4th is the latest i think, such a sick concept, would love to ski july forth then booze cruise on the lake all night
 
all depends on how good of a spring its going to be... we (the sierras) are supposed to get a couple storms in the next couple of weeks, but if thats it then it will prolly close in june, Memorial day at the earliest i know that.
two years ago when it it was open till the 4th of july it was an epic march.
you should be good.

 
but march and april are still snow months too.

I would say second or third sunday of june, unless they get a lot mre and decide to rip till the 4ht of july again.
