Parts of Denmark, Scania and the Norwegian coast line were free from ice around 13,000 BC, and around 10,000 BC the rim of ice was around Dalsland, Västergötland and Östergötland.
It wasn't until 7000 BC that all of Svealand and the modern coastal regions of northeastern Sweden were free of ice, although the huge weight of the ice sheet had caused isostatic depression of Fennoscandia, placing large parts of eastern Sweden and western Finland underwater.
The northern hunter/gatherers followed the herds and the salmon runs, moving south during the winters, and moving north again during the summers.A blazing fire was not the only thing to keep Bronze and Iron Age Scandinavians warm through long cold winters.From northwest Denmark, circa 1500-1300 BC, to the Swedish island of Gotland as late as the first century AD, Nordic peoples were imbibing an alcoholic "grog" or extreme hybrid beverage rich in local ingredients, including honey, bog cranberry, lingonberry, bog myrtle, yarrow, juniper, birch tree resin, and cereals including wheat, barley and/or rye -- and sometimes, grape wine imported from southern or central Europe. The Neolithic stage is marked by the Funnelbeaker culture (4000–2700 BC), followed by the Pitted Ware culture (3200–2300 BC).The period 2500–500 BC also left many visible remains to modern times, most notably the many thousands rock carvings (petroglyphs) in western Sweden at Tanumshede and in Norway at Alta.
