Mammoth Mountain is one of the best. This mountain has the best snow, and the best slopes. My fiance is a snowboarder, that can't ever get enough snow. At a time he had a season pass to this mountain, and we live over 100 miles from the resort. This resort has some of the nicest staff, and some of the greatest accommodations. The best part, the ski season lasts until July when most resorts are closed by April!
