The Aletsch Glacier (Aletschgletscher) or Grosse Aletschgletscher) is the largest glacier in the Alps. It has a length of about 14 mi, has about a volume of 3.7 cubic miles, and covers about 31.5 square miles in the eastern Bernese Alps in the Swiss canton of Valais. The Aletsch Glacier is composed of four smaller glaciers converging at Concordia Place, where its thickness was measured by the ETH Zurich to be near 1 km, 3,300 feet. It then continues towards the Rhône valley before giving birth to the Massa. The Aletsch Glacier is – like most glaciers on this world – a retreating glacier. As of 2016, since 1980 it lost 0.81 miles of its length, since 1870 2.0 miles, and lost also more than 980 feet of its thickness.
