How did retreating Pleistocene glaciers affect the earliest settlement of Denmark?
The retreat of the great glaciers during the Pleistocene Epoch was the primary environmental catalyst for the earliest human settlement of Denmark. As the climate warmed and the ice sheets receded, the landscape became habitable for the first nomadic hunters, who arrived in the region by approximately 12,000 BCE.12
The glacial retreat also fundamentally shaped the physical geography of the area. As the Weichsel glaciation withdrew, it deposited layers of soil over the underlying chalk and limestone, creating the low, hilly, and fertile moraines that characterize much of the Danish landscape today. This process created a distinct contrast between the fertile loam plains of eastern and northern Denmark and the flatter, sandier regions of western Jutland, which were formed by meltwaters pouring from the shrinking ice sheet. These environmental shifts provided the necessary conditions for the subsequent development of hunter-gatherer societies and, eventually, the transition to a settled agricultural culture during the Neolithic Period.312
