When Did Mammoth Close In 2024 Season. Mammoth mountain, california will have its first day of the season on november 15, 2024, and riders will have five fresh inches of snowfall to celebrate in. One of the main stats i have always loved to examine is the opening and closing dates at mammoth.
Only twice before has the ski area stayed open. Facilities close at the end of the last business day listed, except campgrounds, which close at 11 a.m.
