In California, Squaw Valley USA is once again offering the longest ski season in Lake Tahoe, as the resort plans to stay open for skiing and riding through to May 10th. Squaw Valley's annual snowfall of 450 inches (1130cm) and mountain topography featuring acres upon acres of upper elevation North-facing terrain are among the natural attributes that enable the resort to remain open through the middle of May each ski season. Base depths currently measure 125-135 inches (325 - 355cm) on upper elevations. The US National Weather Service is calling for snow this weekend, April 24 through to April 26th.
In Canada the four West coast resorts still open are Jasper, Lake Louise and sunshine in Canada and whistler in British Columbia. All but Jasper are open in to May and all have had more fresh snow in recent days with low temperatures helping to maintain snow integrity.
On the East Coast Killington in Vermont and Mont Sainte Anne in Quebec are both still open.
Although it's May next week, more fresh snow is forecast for Western North America and for the Alps in the next few days.
