A few corrections for your readers. Most of January, February, and March remain guided-only at Silverton Mountain, but December, early January, and April are unguided at about 40% of the price of guided skiing/riding. There is snowcat skiing available in Silverton (silvertonpowdercats) but not at the ski area itself. And finally, while my most precious possession is my made-in-Silverton Venture Storm Splitboard, all hiking at Silverton Mountain is bootpacking and requires no splitboards, snowshoes, or AT gear of any kind. Just bring your beacons, probes, and shovels if you've got 'em . . . rent 'em from the ski area if you don't.
Best Hikeable Terrain Denver 2010 - Silverton Mountain
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.
