From the top of Dinwoody pass you descend down a snowfield onto Dinwoody Glacier. From the glacier head north towards the base of Gannett. There is an obvious band of snow that connects Dinwoody Glacier to Gooseneck Glacier that you need to cross to begin the steeper part of the ascent. Once you cross the snow band, begin heading up the glacier until you are at the base of the couloirs that head up the southern flank of Gannett. Take the further left of the couloirs. The crux of the route begins here. In order to ascend the couloir you must cross a bergschrund. The 'schrund has a snowbridge over it that is easy to walk over but in the later months the snowbridge melts and can become a problem. Once you cross the 'schrund the climbing is great. Continue to ascend the Couloir to a rock band that is easy Class 3 climbing. Take the rock band north to the main snow covered face of Gannett and climb the snow up to the ridge line. Take the ridgeline over to the summit!

Descend the route the same way but when we started down, (we summited around 10:00 am after a 4:00am start from Titcomb basin) the snow had no bottom to it. The sun had melted it quite a bit and while plunge stepping down the route it was very difficult to get a solid placement with your foot. If you slip and the snow conditions are like this it would be very difficult to self arrest. This is obviously a problem so we just took it slow and made it down without a problem. On the way back down Dinwoody Pass I began to glissade down the snow. I decided to leave my crampons on due to the softness of the snow and knowing that self arresting might be slightly difficult. The run out was really good so I began to glissade down and when I wanted to stop at the end I was digging in my axe for all I was worth and not slowing down very much at all. So I dug in my crampons next and I am very glad I had those on becacuse stopping would have taken a much longer time with just my boots. So anyway, just a side note to be careful with the snow conditions.
Overall this is a great ascent, really a great alpine route!


Our group of 4 started at about 4:00am from the base of Dinwoody Pass, in Titcomb Basin. After several hours of hiking we made it to the top of Gannett at about 10:00am. We descended the same route and made it back to camp around 4:00 the same afternoon.


We didn't use a rope on this ascent due to us being relatively comfortable with the amount of exposure. We did however bring along a rope, crevasse rescue gear, and some assorted snow protection pieces (deadman, etc.). Some parties may wish to rope up for some of the sections. One last note, I know it has been done without, but crampons, helmet, and axe are a must.

My wife and I climbed this route in late August, 1993 and the low in Pinedale the night before was 20 degrees. We started early and it was very cold. Cramponed over the pass and put the rope on for the glacier. The summit ridge was all snow, which I think is unusual. We figured on nice soft snow for our descent (since it was totally clear and windless), but the crux couloir hadn't softened at all! This slowed us down a bit, but even the glacier was still frozen solid at 2PM. We ended up wearing our crampons the whole day.

There aren't any glacier routes like this in Colorado, so I thought this was a lot of fun. Lots of people tramp across the glacier unroped, it's not clear how safe this is, it is a glacier after all.

It is shorter to approach this route from the Inkwells to the east, but hardly anybody does this as you have to get an expensive permit to go through the Indian Reservation. Nov 13, 2006
Stunning country, one of the wildest places I've been. About 24 miles from trailhead to summit - way back in there. Good fishing all along the way! Dec 5, 2006

I did this route in august (1984). Unbelievable amounts of ice and snow everywhere. It snowed on us en route. Hard to believe it was summer in the middle of the U.S. The summit of Wyo is a fantastic place. Feb 1, 2007

I tried this route a few years ago in September, and the Bergschrund was wide open, with no snow bridge. The same was true this year (Sept. 2011), but I was smarter this time, and climbed the S.E. Couloir. Consider this route (the SE Couloir) as a late season alternative. Sep 13, 2011
Just got back from doing this route. I loved it. I wrote up a whole description of my trip, you can read it here.

I hope to return to explore some more of the Winds.

I included a GPX file in my report and maps. I found these difficult to find before I left. Didn't really need the GPX anyway, but the maps would have been nice. Aug 10, 2012

Did the Gooseneck route solo as a car climb 8/27/2013 from the Elkhart Park trailhead using an ice axe and Kahtoola Microspikes. The 'schrund' was passable on an ice bridge to a fixed rope, but the rope wasn't a true climbing rope--just a consumer grade thick nylon rope like you would get at Home Depot for a light-duty rope swing. I was able to free climb this 15 foot 5.6/5.7 section both up and down rather than trust the rope too much. I'm sure the rope would have worked for quick rappel and maybe ascending with prussiks or ascenders. I was lucky the ice bridge and rope were there or I would have turned back. By far the hardest car-to-car climb I've ever done -- makes The Grand easy by comparison. Aug 28, 2013

Did Summit day from the top of Bonney pass. Spent an incredible 2 calm, quiet nights up there. Fantastic. If you can manage to be up there without wind, there is nothing like it on this earth! Sep 8, 2013
Anybody head up to Gannett recently? I'm sure the snow bridge is long gone by now. Any alternative to get past the bergshrund? Sep 10, 2015

On August 16th 2018 the snow bridge was gone for roughly a week, I was able to climb the slabby section to climbers right to bypass the bergshrund. Although the bypass is only 3rd or 4th class I would recommend some small rock pro as the rock was very wet and a fall would be fatal. Aug 20, 2018

Snow bridge is in on East (left side). Snow conditions were fine. Rappelling off East (left) buttress leads to a gaping opening where the snow has separated from the granite (four to ten feet wide). Next day after summiting was awakened by snowfall and high winds in Titcomb Basin. Aug 28, 2018
