Joan O'Neill says there have been a lot of skiers this month at the Thompsonville resort, especially on weekends.
The unseasonably mild temperatures that arrived about a week ago have had more of an affect on southern venues.
Officials closed the Muskegon Winter Sports Complex on Friday and Ottawa County's Pigeon Creek Park on Monday.
