Overview
Archive NoteLambert Glacier receives ice from a vast East Antarctic drainage system and flows into the Amery Ice Shelf. Its measurement depends on whether the terminus is set at the grounding line or the seaward shelf edge.
Guinness describes the 1,470-km total flow line as including approximately 550 km of floating ice shelf; the Amery Ice Shelf itself covers around 69,000 square kilometres. This record measures the linked flow system, not ice-sheet area.
