Gannet Peak S.E. CouloirThis route is an excellent alternative to the Gooseneck Gully route, particularly if the Gooseneck bergschrund's snow bridge has melted out. It may be a bit faster than the Gooseneck route, and obviates the need to ascend chossy rock on the lower Gooseneck ridge. The route is not described in Joe Kelsey's guidebook, but the couloir is easily seen from Bonney Pass.
The route requires a long approach from Elkhart Park or Trail Ranch. Most parties will take 2 days each way for the approach, i.e. 5 days round trip. (Gannet has now been climbed in 12 hours car-to car!) From Titcomb Basin the elevation gain for the climb and the return trip is 5800 feet. This includes the 1400 foot re-ascent to Bonney Pass on the return to Titcomb.
The approach hike is long, but beautiful.The climb involves travel over a relatively safe potion of the Dinwoody Glacier. Unlike the Gooseneck route, this one does require that you negotiate an area of densely packed crevasses. Some of them are deep. The couloir is about 45 degrees in steepness, and gains 600-800 feet of altitude, from the Dinwoody Glacier's N.W. arm to the summit ridge of Gannett. An uncontrolled fall down the couloir would probably be fatal, and there is some potential for rockfall danger.
I descended the S.E. Couloir, and retraced my steps through the crevasses. If you (unlike me) are smart enough to bring a rope, you can descend the Gooseneck gully, and rappel over the bergschrund, instead of descending the S.E. Couloir.
The difficulty of this route will depend greatly on snow conditions. I encountered a surface of corn snow, bonded nicely to an icy/frozen layer underneath, which took my crampons well.
Update 7/6/12: This route was skied in Spring 2012. You can find a nice write-up with some excellent photos at 14'ers.com. Well done, folks! PL
