Pro skier Cody Townsend is on a听mission right now to ski all 50 lines in the 2010 book听. He鈥檚 one year and 20 lines into what he hopes is a three-year project, and he鈥檚听learned a ton so far. Townsend isn鈥檛 the only skier attempting all 50. Utah ski mountaineer听 has been at it for decades and has currently done 30 of the descents. Some of the lines in the book feel practically impossible听due to their remote and challenging terrain, while听others are听literally disappearing due to climate change and rockfall. But a few are pretty attainable for the rest of us鈥攁lbeit if you have proper backcountry-skiing experience and avalanche training. We asked Townsend and Howell for their input on the most doable lines in the book. Here鈥檚 what they recommended.
Mount Shasta, California

A good entry-level ski-mountaineering objective, 14,162-foot Mount Shasta is a volcanic peak at the southern end of California鈥檚 Cascade Range. You鈥檒l spend many hours slogging up 7,200 vertical feet, and you鈥檒l need an ice ax听and crampons to ascend the peak鈥檚 steepest sections. The book cites the Avalanche Gulch route up Shasta, the most popular and straightforward thoroughfare for climbers and skiers come springtime.听 leads trips in April and May (from $145). Sleep in your car at the trailhead or post up at听, a hotel and hostel with on-site camping that opened last听spring (camping from $40; bunks from $50; rooms from $110).
Tuckerman Ravine, New Hampshire

On the southeast flank of 6,288-foot Mount Washington, you鈥檒l find a glaciated cirque called Tuckerman Ravine, a rite of passage for backcountry skiers in the Northeast. It may be the most popular line in the Fifty Classic Ski Descents听book鈥攖his place gets packed on spring weekends. Park at the Appalachian Mountain Club鈥檚 Pinkham Notch Visitor Center, then strap skis to your backpack to hike the three miles along Tuckerman Ravine Trail to the base of the bowl. From there听you鈥檒l have your choice of a number of classic lines.听听(from $325) leads backcountry trips and instructional courses all around Mount Washington, including custom trips into Tuck鈥檚. The听听(from $70) at Pinkham Notch is open year-round and comes with breakfast, dinner, and guidebooks in the library.
Mount Superior, Utah

Drive up Utah鈥檚 Little Cottonwood Canyon on your way to Alta or Snowbird听and you can鈥檛 miss Mount Superior, which towers over the road and beckons backcountry skiers with fresh powder after a storm. This popular Wasatch peak gets trampled with dawn-patrol skiers from Salt Lake City, but you can still find quiet corners and untracked lines in the steep, north-facing听Cardiac Bowl or on South Face, which has lines like Little Superior, Suicide Chute, and Pinball Alley.听听(day trips from $200) guides skiers down the southeast face of Superior. Stay at Alta听at the听 (from $329), which is just steps from the trailhead.
Bloody Couloir, California

It鈥檚 a long approach to the base of 12,552-foot Bloody Mountain, in the eastern Sierra Nevada, before you even begin the haul up the peak鈥檚 signature north-facing couloir. You鈥檒l spot this marquee line from Highway 395 as you鈥檙e heading south from the town of Mammoth Lakes. To get there, drive up a rough, four-wheel-drive-only road鈥攊f the snow is low enough鈥攐r hike or skin an additional five miles and over 2,200 vertical feet to reach the bottom of the 2,500-vertical-foot chute.听 will do private, custom day trips here for clients with enough backcountry听experience (from $475).听听(from $119) has 28 cabins and a restaurant just a few miles from the start of the route.
Seven Steps of Paradise, British Columbia

Rogers Pass is full of excellent ski-touring options. But Seven Steps of Paradise might just be the most classic and doable. You can see the line from the Trans-Canada Highway, making it a popular roadside tour. You鈥檒l start at听Highway 1 at Rogers Pass, hike听to the Asulkan Hut, and then top out on the headwall of 9,245-foot Young鈥檚 Peak, gaining over 5,000 feet in elevation along the way. Stay overnight at the Alpine Club of Canada鈥檚 backcountry听听(from $35), which will take you a few hours on skis to reach. Seven Steps of Paradise is easily accessed from the hut.听 leads group day trips all over Rogers Pass (from $299).
Silver Couloir, Colorado

Like many of the lines in the book, this one is hardly a well-kept secret. Despite the potential crowds you鈥檒l find here, it鈥檚 still as aesthetic as a couloir gets. You can see the Y-shaped Silver Couloir on the northeast side of 12,777-foot Buffalo Mountain as you drive west through the Eisenhower Tunnel on Interstate 70 in Colorado鈥檚 Summit County. The 3,000-foot-long, relatively wide line reaches about 45 degrees in steepness.听听(half-day trips from $220) will escort you there. Stay in the town of Silverthorne at the听听(from $70), a five-room lodge run by a backcountry skier.
