Sherpas and climbers scale the Khumbu Icefall at the foot of Mount Everest. The Icefall is a fragile set of ice blocks as big as buildings, which slowly move against each other, and thus make it one of the most dangerous parts of the climb. Due to the 2014 release of an ice serac - a column of glacial ice - on to the Icefall, which killed 16 Sherpas and porters, a new route was found in 2015 further to the right of the Icefall. This image was taken five days before the devastating 7.8 magnitude earthquake hit Nepal and destroyed the new path, halting all climbing of Mount Everest from the Nepalese side, for the second year running. The route was opened again in 2016.
