A goat rests at the Platta viewpoint as a group of hikers (background on R) trek in the distance on the Aletsch Glacier in Fiesch, Switzerland, August 12, 2015.

The glacier, 900 metres (2,950 feet) thick at one point, has retreated about 3 km (1.9 miles) since 1870 and that pace is quickening. REUTERS/Denis Balibouse TPX IMAGES OF THE DAY
