Lambert Glacier is a major glacier in East Antarctica. At about 50 miles (40 km) wide, over 250 miles (400 km) long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier. It drains 8% of the Antarctic ice sheet to the east and south of the Prince Charles Mountains and flows northward to the Amery Ice Shelf.[1] It flows in part of Lambert Graben and exits the continent at Prydz Bay.
