Our destination was the summit of the Grand Teton in Teton National Park, WY. At 13,775 feet above sea level, we'd have a 5,000 foot hike over 7 miles and then 2,200 feet of technical rock.
We took a day to hike in. Then we got an alpine start on the Petzoldt Ridge, an exposed 800 foot rock route leading to a more moderate 1,200 feet on the Upper Exum Ridge. Almost 14 hours later we were back at our camp.
