Is it enough like October 2004?
No. MMSA reports 6 inches at Main Lodge with another 3-7 expected. OpenSnow yesterday thought Mammoth would get 20 storm total. In 2004 there were 56 inches new snow third week of October and another 26 during the fourth week.
Do Private equity-owned ski areas even hire before October? It does not fit into a model.
Alterra says it lets the individual areas make these decisions. I have tracked the phasedown of lift operation in the spring/summer in minute detail and current philosophy (2017 and later) seems similar to the Dave McCoy years. Mammoth was lightly less aggressive in late season operations during the early Starwood years (2007-2013) when it was most leveraged.
I know a little about the seasonal employees because my son Andrew was one from Dec. 2020 - Apr. 2023. He showed up for training on Nov. 30 and was on duty about 2 weeks later. Most seasonal staff is laid off at the time of Canyon/Eagle closing, which is the later of: second weekend of April, and one week after Easter. They look for some volunteers among that seasonal staff to hang on though May, which Andrew did in 2021 and 2022.
Under Dave McCoy permanent employees are available to run lifts when conditions permit. In spring that generally means running extra lifts on weekends, particular Memorial day, to handle the crowds. Past Memorial Day I heard that grooming had to be cut back some because those employees can get lucrative summer construction jobs.
As for early season under Alterra, ChrisC must have forgotten about
4 years ago. That was a big atmospheric river, and Mammoth was so confident that they announced the October 29 opening day a week in advance before the storm hit. The storm was a bit warmer than advertised, not enough to open chair 2 parking even though there was 4+ feet of snow above 10,000 feet.
The above scenario is obviously handled with permanent staff. With the
huge 2004 snowpack and during another
good November in 2015, lift operation did not go past chairs 4 and 10 until Thanksgiving. So I believe some staff is hired to be available at Thankgiving if they can open Canyon Lodge, even though full staffing might not be until mid-December.
