Below are pictures from a back to back summit of Shishapangma (14th tallest at 8,008m / 26,289 ft) and Cho Oyu (6th tallest at 8,201m / 26,906 ft) in October 2011. I summitted Shishapangma on October 4 and Cho Oyu on October 12 with Mike Hamill of IMG – the last person to do so was Ueli Steck. This expedition began on August 26th and was the hardest.
