With a current base depth of 120โ at Main Lodge and 270โ at the summit, Mammoth will be operating DAILY into August for one of our longest seasons in history. When will this endless winter end? We donโt have that answer yet, but we do know that the skiing and riding is all-time right now. Get out there and get your summer shred on with us.” – Mammoth, today
