The most technical line in the Great Gulf. Turkey Feather is a variation of Turkey Chute that is closed off by ice bulges at the bottom. A downclimb or rappel is usually necessary, but fat conditions sometimes offer a way to sneak through. From the top of Turkey Chute, traverse hard right to the shoulder. Drop into the gully, ever steepening turns in a tight chute bring you to the top of the ice. A little down climbing may be necessary to reach V-threadable Ice. One rappel with a 60m rope gets you over the first ice bulge, the second ice bulge can usually be skirted to skiers right. This deposits you in a snowfield above the boulders, where you can traverse skiers left to the bottom of Turkey Chute/Airplane Gully. Shake off the rope work with some nice turns to the bottom. Be aware that this is a complex line in a remote wilderness area, with no realistic exit out the bottom. This should only be attempted in the best conditions, by skiers who are experienced ski mountaineering terrain.
