Mt. Snow’s forecast shows a consistant pattern of colder weather compared to Killington and Sugarbush. Even though K has an elevation advantage, they won’t be able to make snow enough snow across the mountain with limited time this week. Not sure about Mt. Snow either but if I had to guess, they have a bit better of a chance of opening. To shredmonkey’s point, he’s right about the profit already being there with pass sales, but you can’t sell passes and then open on only natural snow on a much later date than normal. They don’t have to rush, but they should give an attempt to open.
