Mammoth, 3 weekends a month, 675 for a pass.
That is only if you are in the MVP club, which is grandfathered in. You have to buy your pass by the end of April. Sometimes they open the club up to new members.
I ski Mt. Baldy one weekend a month. It is 120$ for a virtual pass. A virtual pass means you have to go on line and make a reservation the night before. You can only have one reservation in the system at a time, so you can't just mark every weekend day. There is a limit on the number of reservations, so you could get blanked, but I have never had that happen. I think it is 500$ for a full season pass.
