Archaeologists tend to refer to the land that once existed between Britain and the continent as a landbridge. It was, however, a landscape as habitable as neighbouring regions, and here called Doggerland to emphasise its availability for settlement by prehistoric peoples. Evidence from the Geological Surveys undertaken by countries bordering the North Sea Basin, together with allied research, is drawn together to provide an overview of the possibilities. A range of interacting geological processes implies that the present-day relief of the North Sea bed does not provide a sound guide to the relief of the former landscape, nor to the chronology and character of its submergence. A series of maps accompanies the text to provide a speculative reconstruction of the topography, river systems, coastline, vegetation, fauna, and human occupation of Doggerland from the Devensian/Weichselian maximum to the beginnings of the Neolithic.
