What Is the Largest Glacier in the World?

The largest glacier in the world is Lambert Glacier, as of 2014. It has a maximum width of about 60 miles and spans a total length of approximately 270 miles. This glacier is over 8,000 feet thick at its deepest point.

Lambert Glacier is located in Antarctica. It primarily moves at a pace of between about 1,300 and 2,600 feet per year, making it one of the most swiftly moving glaciers found worldwide, despite its great size. The glacier was first noticed when an American geographer was examining pictures taken of Antarctica from a U.S. Navy operation in 1947. The glacier was initially named Baker Three Glacier in 1952, in reference to a Navy code name, and it was renamed in 1957.
