A simple grayscale map of the world entitled “The Peak of the Last Ice Age, 20,000 years ago”. The dark shaded areas indicate ice sheets, and the light gray shaded areas indicate dry land then, that is under the sea today. A look at the map shows that most of the land masses had a thin sliver of land running around the coastal areas that was above water. This was particularly pronounced around Indonesia (Sundaland) and South East Asia, and also above Australia (Sahul). Another remarkable area is the amount of land projecting off Asia and Europe into the Arctic – with Beringia quite large – and also a fair amount of land that is now underwater near the British Isles and France. Ice sheets are prominent, too, with the Laurentide Ice Sheet covering most of North America. The Greenland Ice Sheet covers Greenland. Scandinavia, the British Isles, are all covered in ice sheets, and the Barents Ice Sheet projects all the way down from the North Pole to reach Scandinavia. In South America, the Patagonian Ice Sheet stretches up the west of the continent, and the Antarctic Ice Sheet covers that continent. Scattered ice sheets occur throughout the interior of Asia.
