All major ski resorts in the Mountain State will be open for winter sports activities by Christmas Day. As locations begin to resume operations, resorts will be making snow to open as many trails as possible. Visitors can check local snow reports to see what trails and activities are currently available. The White Grass Ski Touring Center in Davis was the first winter sports facility in the state to open on Nov. 18 and has 48 trails. Snowshoe Mountain began operations on Thanksgiving Day with more than 60.
