Replying to How long will mammoths park be good

Every summer my homies and I usually take a trip to mount hood in the middle of June. But we were thinking this year since theres so much snow in mammoth and they've already announced they'll stay open till the fourth of July we might venture out there. Reasons why we are thinking mammoth is because we would then drive down to LA and hit the beach. In past seasons with good snowfalls how long has the park been good? How long has skiing around the mountain stayed decent?
Thanks
