It’s an endless winter in the West. Snow from the barrage of storms that pounded the western mountains over the winter is still on the ground. Many mountains in the Rockies, Sierra and Cascades are packed with at least 8 feet of snow, the National Weather Service said, creating a dream summer for skiers and snowboarders. The Mammoth Mountain ski area in Mammoth Lakes, Calif., is seeing its “best spring conditions in decades … and will be operating DAILY into August for one of our longest seasons in history,” the resort said on its website.
