Welcome to the "sidecountry": A single lift takes you part of the way to Silverton Mountain's seemingly endless powder stash, but you'll be hoofing it in guided groups to get to the goods from there. Avalanche gear is mandatory and available to rent, and you'll want to break out your big boards. There are snowcat and heli-ski options available, but we recommend you do as the locals do: Use the Storm split board from Silverton's Venture Snowboards — designed with Silverton Mountain in mind.
