The Lambert Glacier (originally Baker 3 Glacier) is a glacier located in Antarctica . At 420 km long and 90 to 130 km wide (inland) it is the longest and largest glacier on earth .
The ice flow is in East Antarctica. From the central dome-like plateau of Antarctica, known as the polar plateau , or from the American highlands there , the ice flows past the Prince Charles Mountains in the west and Princess Elisabeth Land in the east towards the coast of the continent, where it joins the Amery Ice Shelf flows out.
The catchment area of the Lambert Glacier comprises around 10 percent of the Antarctic ice sheet . At its confluence with the icy Southern Ocean , where the ice moves around 750 m to 1000 m per year towards the sea, the glacier is around 210 km wide.
Aerial photos of the glacier were taken during the US operation Highjump (1946–1947). These were used by the American cartographer John H. Roscoe (1915-2007) for an initial mapping. Australian cartographers re-mapped in 1956. The Antarctic Names Committee of Australia named the glacier in 1957 after the Australian geodesist Bruce Phillip Lambert (1912-1990), head of the cartography department in the Australian Department of National Development .
