The silt in this ice core is 2.7 million years old. Researchers think it represents an ancient, tundra-like soil buried under the Greenland ice sheet since the first glaciers formed on the island.

This tundra landscape in western Greenland may be similar to the one overrun by the Greenland Ice Sheet at Summit more than 2.7 million years ago.

In July 2008, the Greenland Ice Sheet was rapidly melting near Kangerlussuaq, releasing large amounts of silt from the basal ice.
