Highlights
A beautiful line you can see from the highway. The sliver is a Teton classic that sees a lot of traffic. However with slopes reaching near 50 degrees it is in prime avalanche terrain and should only be tackled by the experienced backcountry skier. The widest section depending on the snow year, can be 10 yards to 20 yards max with granite rock on both sides. The skiable vert mentioned above is only for the couloir. You get about 3000 skiable vert back down to the trailhead, but it is not as continuous as one would like.
Ascent
From Moose, head into the Grand Teton National Park and head north until the road is closed. Park at the Bradley/Taggart lakes trailhead. Follow the cross country trails bearing north and you want to end up on the ridge that separates the two lakes. Follow this ridge until you hit the treed face of Shadow Peak. Switchback up the face until you reach the top of knoll of Shadow Peak, now being able to see the sliver while looking west. Head south until you find an entry couloir that will take into the cirque at the base of the Sliver. Now boot up the Sliver as high as you want.
Descent
Ski the couloir and then exit by heading north out of the cirque. Hug skiers right once out of the cirque and pick your way through trees and cliffs. Be sure you have scoped this area before you try it as it is easy to get cliffed out. Eventually you should find your self at Bradley Lake. Cross the lake by heading east and regain that ridge that seperates the lakes at the eastern end. Follow your tracks back to the parking lot.
Access/Permits
You will need a National Park Permit to get to the trailhead.

Yesterday we skied the Sliver in variable conditions. Good turns in the shade at all elevations encountered... powder dust on sun crust down low. Dangerous accumulations on the sun crust in windloade...[view] Warpigsinfin: January 21, 2010 Uphill: 5,000 ft. | Downhill: 5,000 ft.
It snowed 3-4 in at the Village but 6-8 up in the high peaks... with a bit of wind slathering the lucky couloirs with 2-3 feet.We skied the Sliver again in blower... couldn't even find the old booter ...[view] Warpigsinfin: January 20, 2010 Uphill: 4,500 ft. | Downhill: 4,500 ft.
We summited Shadow to find the Sliver looking delightful. Closer examination showed two folks booting up it. We dropped into the Cirque and waited for them to gear up and ski the line... it was Greg...[view] Already have a blog about this area?

Guide Books

People die skiing in the backcountry every year. Avalanches, crevasses, trees, human error, weather, tree wells, rabid sasquatches, among other things can kill you in an instant. Use this guide at your own risk, we are not responsible for any wanker getting all wanked up in the wankin' backcountry. That being said, even the most experienced backcountry skier can get caught off guard. Take avalanche classes, carry a beacon, probe, shovel and avalung AND KNOW HOW TO USE THEM. Just because you buy them, doesn't mean you get magical powers of invincibility. Many people who own beacons have no clue how to operate them. More importantly than any gear you can buy, you need to know how to safely travel in avalanche terrain, minimize potential hazards, and interpret how weather affects the snowpack. This requires time and experience. Learn from others, be safe and courteous, and when in doubt go home and live to ski another day. The amount of snow needed to be dug up to rescue a buried victim, on average weighs right around an actual ton. In North America 25% of victims die from hitting trees, rocks, and other sharp unforgiving surfaces. It only takes one miscalculation to have the mountains kick your ass. Just because you see tracks or someone else skiing a line, does not mean you should ski it. Remember, individual actions affect all of us. Take care of each other out there, we are all on the same team.
