From Mammoth Snowman:
Coverage out on the hill is thinning in some areas, especially below the 9,500-foot level.
The current base at the 9,000-foot level is now down to a shocking 38 inches with 5-7+ feet of base over the upper mountain.
Chairs 22 and 9 are now closed until the mountain receives more snowfall. The Little Eagle area is about toast, with only a thin ribbon of snow at the bottom. I don’t see chair 15 running after this weekend, unless they truck in some snow.
>> If you’re wondering how long Mammoth will stay open this season, they have plans to stay open until Memorial Day. To make that happen it needs to cool off and more snowfall.
My comment: I believe the upper mountain will last to Memorial Day unless the abnormal heat persists for an extended period. Mammoth may need to be willing to run the lower gondola for transport as during the 2017 and 2023 August closings.
Current snowpack is better than at this time in 2012, 2014 and 2015, all of which made it to Memorial Day though very marginal. Mammoth announced a May 10 closing in 2015 but extended after an 18 inch May storm.
