About 15000 BC we see the beginning of the so-called post-glacial age: the melting of the ice became more constant, the sea temperature rose, and the climate along the Greenland coasts improved. [...] As the ice retreated farther into the interior of the country the shores of the fjords, the valleys and the stretches of land behind the foreshore began to turn green, though the verdure still kept a respectfid distance &om Storbr~en, the Greenland Ice Cap. [...] The hunting of the mammals of the sea, the seal and later the whale, called for one type of implements: the harpoon, the hook and the fish-spear; the hunting of terrestrial mammals, especially the reindeer, demanded weapons of another kind: the hunting spear and the bow and arrow. [...] However that may be, the reindeer were more numerous than today on the Nflgssuaq Peninsula and south of this along Disko Bay; at some point the animals spread along the entire West coast, their migration route perhaps taking them round the southern tip of the country and northwards along the East coast until their way was blocked by the Blosseville coast; and man followed in the tracks of the rein [...] Then the stillness was broken again by human speech, by the sound of the stone cutter's hammer, by the tinkling of the flint flakes split off the core with the flaking tool.
