The first major storm of the season has hit the Sierra. Mt. Rose, Nev., opened Nov. 4 thanks to as much as 17 inches of snow augmented by snowmaking. Guests can take advantage of $10 lift tickets from 9 a.m. to 4 p.m. and can access one trail by riding the Flying Jenny Conveyor lift.

California’s Mammoth Mountain opened today, Nov 5, a week ahead of schedule. The first chair and annual banner-breaking event took place at 8:30 a.m. at the Broadway Express lift. Opening day tickets cost only $50. Boreal, Calif., will open on Nov. 6, with at least one run and six terrain park features. Mountain High, in SoCal, also plans to open for the weekend on Nov. 6; it will evaluate conditions on Sunday before deciding on operations for the following week.

The first resort to open in western Canada is Mt. Norquay, in Banff, Alberta. The ski area opened today for its 90th season. Meanwhile, nearby Lake Louise Ski Resort is scheduled to open on Nov. 7.

Colorado’s Keystone Resort will also open Nov. 6. Chairlifts will start running at 9 a.m., but guests are encouraged to come early for a chance to win prizes. The first 500 people in line will receive a reusable Keystone water bladder. Wolf Creek Ski Area in southern Colorado also intends to open this weekend, on Nov. 7.

Killington, Maine’s Sunday River, and Quebec’s Mont-Saint-Sauveur, all of which opened during October, have ceased all operations for the moment. They will re-open for the season once the local weather cooperates and ski conditions improve.
