The Tram Face is on at Big Sky. Photo by Chad JonesSnow is a scarce commodity in California and Colorado this early winter, but resorts that have already received a healthy amount wants to gloa... uh, "share." This January, anyone with an Epic Pass from Vail Resorts skis free at Montana's Big Sky.

"We've been really lucky," says Greer Schott, Big Sky's public relations coordinator. "Our thinking was, 'Let's share this.'" Big Sky has nearly 90 percent of its terrain open, and all chairlifts are operating. A big dump just before Christmas set the resort up for record numbers over the holiday period, and a 30- to 45-inch base on the 3,000-plus acres open.

Epic Pass holders ski free when they book lodging with Big Sky Central Reservations. (Ask for the Epic package.) Anyone included in the pass holder's lodging reservation can ski for $74 per day. Don't know anyone with an Epic Pass? Call and ask if they'll honor your local ski pass. Hey, they want to share.

And that's not all: Red Mountain in British Columbia is also offering free skiing for all Americans until February 4. Any U.S. resident who books lodging through Red Mountain with the promo code "RedsGotSnow" receives free day tickets for each day they stay. (Why ski Red? See the "Ski Locally" feature in Mountain's Winter 2012 issue, on newsstands now.)

"The last few weeks there's been such negative press," says Red CEO Howard Katkov about snow conditions in the U.S. "There's not a lot of smiling faces out there. We though, we have good snow—let's give everyone an offer to come up and see Red Mountain and Rossland, which is a phenomenal town with great people." Red has received 85 inches of snow this season, and all 88 trails are open.  —Olivia Dwyer
