Snowmaking is essential to the success of Southern California's Resorts and nobody does it better than Mountain High. This is why we have traditionally been the first resort to open in Southern California for more than a decade. Here's an important thing to note: SNOW MADE AT THE RESORTS IS REAL SNOW. There's nothing artificial about it. We use the same elements as Mother Nature to make snow all season long and create an environment where itâ??s WINTER EVERY DAY, even when its nice and warm where you are.
