Parts of Denmark, Scania and the Norwegian coast line were free from ice around 13000 BC, and around 10000 BC the rim of ice was around Dalsland, Västergötland and Östergötland.
In Scandinavia, the time following the ice age begins at circa 9500 BC and is called at first the Yoldia Stage, after the Yoldia Sea, then the Ancylus Stage, after the Ancylus Lake in turn named after Ancylus fluviatilis, a small fresh-water gastropod from this time.
