“One of the Very Best Mountaineering Adventures!”

Jerome and Ty of Wind River Climbing guides are excellent Gannett Peak Expedition guides. It was a technically challenging and very strenuous summit day and having Jerome and Ty to guide and encourage us made all the difference for a successful trip. Nicholas was a great porter on our trip, which really helped to conserve our energy for the summit day. This was one of the very best mountaineering adventures that I have ever done. I would definitely have Jerome and Ty guide us on another trip.
