The Azores group as the site of the Island of Atlantis.
Christian O'Brien, a retired industrial geologist, archaeologist and historical writer, has also tackled the concept of a mid-Atlantic continent having once existed in the vicinity of the Azores. In his 1997 book "The Shining Ones" - co-authored with his wife Barbara Joy - he proposed that the Azorean landmass, as he sees it, suffered immense cataclysms and eventually sank into the earth's liquid magma, leaving only the Azores as hard evidence of its former existence. The discovery of six fields of hot springs in the vicinity of the Azores is, he postulates, firm evidence of this hypothesis.
During underwater explorations off the island of São Miguel, the largest island in the Azores group, in 1971 Christian O'Brien found clear evidence of an underwater river bed filled with water-worn boulders. By applying detailed contouring methods to hydrographic charts, the O'Briens discerned that rivers draining off the southern slopes of São Miguel once converged together in a huge valley, now situated some 64 kilometres out from the present coastline. Other islands in the Azores group have yielded similar hydrographic anomalies, and in one case the O'Briens even traced a series of river valleys which extended for a distance of 288 kilometres before converging together in a much larger river basin.
With a knowledge of ancient river systems, the O'Briens were able to reconstruct a land profile which revealed an Azorean landmass 'about the size and shape of Spain', with high mountain ranges rising over 3655 metres above sea-level, as well as impressive rivers that run 'in curving valley systems'. Furthermore, they have pointed out that:
In the southeast, a feature which we have called 'The Great Plain' covered an area in excess of 3500 square miles [9065 square kilometres], and was watered by a river comparable in size to the River Thames in England. It has, as we shall see, points in common with a great plain described by Plato in his Critias, as being a feature of the island of Atlantis.
The conclusion drawn from these findings is that the Azores once formed part of a much greater landmass which sank beneath the waves and is now situated 'many thousands of feet' below the current sea-level. To obtain a more substantial insight into this fascinating subject, the O'Briens propose that a scientific team take a series of core samples from the proposed sites of their river channels. They confidently predict that these will show not only evidence of ancient river beds, but also of the freshwater flora and fauna which once thrived on the former Azorean landmass.
These are fascinating insights into the protohistory of the Azores group.
