These maps are based on the recently published book by Robert John Langdon titled 'The Stonehenge Enigma' which proves that Britain suffered massive 'Post Glacial Flooding' directly after the last Ice Age ten thousand years ago, and that mankind placed their ancient sites on the shorelines of these raised waterways.
The maps are presented on the old ordnance survey first edition that shows the natural ancient environment to a higher degree of detail than subsequent editions. The newly added waterways are colour coded to show how the land would have looked in both the Mesolithic Period (10,000BCE to 4,500BCE) and the Neolithic Period (4,500BCE to 2,500BCE).
