On an average fresh-powder morning at Little Cottonwood Canyon (and there are lots of them), the snow at Snowbird is tracked by noon. But it's no big deal. What remains is dry and easy to bury an edge into, and you can still find great lines between the trees on Soma Trophic Hormone (aka STH or Steeper Than Hell), or in the wide-open spaces of the Cirque. And starting this season, you can buy the Alta Snowbird Ticket, which lets you ride the new Mineral Basin lift to the top of Sugarloaf Saddle. From there you cross over into Alta Ski Resort, and then hike and traverse about 30 minutes toward the open steeps of East Devil's Castle, the off-angle face that ski patrollers open when the snowpack has settled.
The new dual-resort passes are for skiers only; Alta still stiff-arms snowboarders. But any experienced group of two or more boarders or skiers can cross through gates above Snowbird's Gad II lift and explore the 2,200-acre White Pine Canyon backcountry. After huffing your way to the top of chutes like Birthday (1,000 feet) and Tri (1,500 feet), you may find a crowd of heli-skiers beat you to the prize. Don't sweat it. There's plenty of snow, and you get it for $600 less than they do. Peter Oliver
Park City Mountain Resort
PARK CITY, UTAH
The closest thing to raw terrain inside Park City's closed boundary lies above the sprawling corduroy off Jupiter Peak, the most prominent feature on the resort's major ridgeline. Because the peak is accessible only by scramblingat least ten minutes from the top of the Jupiter liftthe 45-degree chutes on the east face (the steepest at Park City) remain untracked for days after a storm. Once those are worked over, head farther east along Pinyon Ridge to the new Black Forest Glades, a low-angle intermediate area with widely spaced trees. If you need a sure powder fix, head west from the top of the Jupiter lift, and then traverse and hike 25 minutes along Pinecone Ridge. On clear days, sunshine quickly turns the west-facing slopes to slush, but so few skiers venture in this direction that fresh tracks are almost guaranteed. P.O.
Vail's commercial success (1.6 million skier visits last year, 20 percent more than any other U.S. resort) is based on the front side's groomed cruisers, but it's the adjacent backcountry, unmanicured Back Bowls, and now Blue Sky Basin that bring in the experts. Blue Sky Basin, which opened amid much controversy over the last two winters, features 645 acres of powder served by four high-speed quads. The terrain faces north and stays largely ungroomed because every run weaves through trees. Huge and varied though Blue Sky is, some locals feel it's a relatively minor addition to the 2,700 acres and 1,850 vertical feet of the Back Bowls that they've carved for years. These monsters stretch six miles east to west, the biggest single swath of lift-served terrain in North America. Southern exposure means the snow here changes fast: If it dumps on Monday, you'll ski powder on Tuesday, crust on Wednesday, and junk on Thursdaythe entire palette of off-piste snow in a few days. For an epic final run, link in-bounds off-piste with thousands more feet of backcountry. Blue Sky Basin, Game Creek Bowl, and Mongolia Bowl all have inconspicuous access gates opening onto thousands of acres of unpatrolled wilderness that lead down to roads. Seth Masia
Telluride Ski Resort
This year the new Gold Hill lift will take skiers directly over what used to be a hidden stash that locals dubbed Claude's Couloir. From the top of Gold Hill you'll be able to dive into Claude's and other formerly hike-to chutes like Electra, Dynamo, and Little Rose. If by chance the snow is stable (which usually isn't the case; the San Juans of Telluride are the most avalanche-prone range in the Lower 48), the ski patrol will let you trudge out of bounds up the ridge to Palmyra Peak for a 40- to 50-degree descent down 3,000 feet of open summit slope. Last year, after Telluride announced its intentions to install two new lifts, it opened this backcountry access gate for those mourning the development of the other new lift, Prospect. (If you're not an avalanche expert, stick to Prospect: It drops you above intermediate glades and beside four short double-diamond chutes.) Head up Palmyra unprepared and locals will chew you outnot because they care about your fate, but because you might trigger an avalanche above them. S.M.
Aspen, with its Learjets and $20 million mountain hideaways, still lives up to its reputation as the Gomorrah of the Rockies. But don't be fooled. With four mountain resorts only 15 minutes from townAspen Mountain (sometimes called Ajax), Buttermilk, Snowmass, and Aspen Highlandsand vast backcountry, much of it in the 181,000-acre Maroon BellsSnowmass Wilderness, the Aspen area remains one of the best places in Colorado for serious big-mountain skiing.
Expert locals and a handful of adventurous visitors head beyond the warning gates on the western perimeter of Snowmass, where rock-lined couloirs plunge 4,000 feet into the East Snowmass Creek drainage. Or they hike five minutes from the High Alpine lift to reach the bowls of West Willow Basin, equally steep and hazardous, but where they're less likely to get stranded above a cliff.
Two years ago, Aspen Highlands extended its boundaries to include Highland Bowl, a steep, east-facing, avalanche-prone swath of mostly treeless terrain atop 12,382-foot Highland Peak. This used to involve a 45-minute experts-only hike from Loge Peak lift to the top of Highland and Bowl. Now it's a 20-minute experts-only free snowcat ride and a 20-minute hike. P.O.
