The extension would mark 199 days of skiing and riding for the 2009/10 season, two days short of Snowbird's record 2004/05 season when the resort stayed open for 201 days until July 4. As of May 20, Snowbird's mid-mountain base stands at 117 inches with forecasts calling for flurries throughout the weekend.
It's the third year in a row that Snowbird has surpassed its annual average in snowfall.
Other US resorts still open include Mammoth Mountain in California which has announced it will aim to stay open to July 4, and Arapahoe Basin in Colorado, which reported a few inches of fresh snow this week and plans to stay open in to June. Timberline Mountain in Oregon is open year round except for a few weeks maintenance closure each September.
North of the border the ski season has ended in Canada with Sunshine ski area near Banff the last to close on Monday, following Whistler Blackcomb's season ending on Sunday. The famous British Columbian resort celebrated its second snowiest winter ever and will re-open for glacier skiing in a few weeks time.
