This book discusses several megalithic sites in southern England and Carnac, France, and their relationship to areas of higher permeability (concentrated flows) within the groundwater. In spite of diverse beliefs and environments, as well as, during different historical periods, various aspects of cultural uniformity prevailed which are associated with this concept. Johnson and his colleagues have investigated sites throughout the United States, Canada, Peru and Chile, as well as, in Europe and East Africa. This data strongly suggests this was an ancient universal human concept which aligned the under, present and spiritual worlds. The English sites include Stonehenge, Avebury Complex, Maiden Castle, Carn Euny Iron Age Village, Drizzlecombe Stone Rows and Cerne Abbas Giant among others. The Carnac sites include the Mene, Kermario, Kerlescan Alignments, the Locmariaquer Megalithic Complex including La Table des Marchands Dolmen, Grand Menhir Er-Grah and Er-Grah Tumulus and several additional tumulus and dolmens. The book includes one hundred-forty eight colored images including maps and stone features.
