The Greenland ice sheet is a vast body of ice covering 1,710,000 square kilometres, roughly 80% of the surface of Greenland.
It is the second largest ice body in the world, after the Antarctic ice sheet. The ice sheet is almost 2,400 kilometres long in a north-south direction, and its greatest width is 1,100 kilometres at a latitude of 77°N, near its northern margin. The mean altitude of the ice is 2,135 metres. The thickness is generally more than 2 km and over 3 km at its thickest point.
