RootsE of Cataclysm 

In Roots of Cataclysm, a journalist investigating the mysteries of the Ice Ages and the first human settlements of the New World finds that conventional doctrine is in conflict with the historical data. He presents a useful and easy-to-follow introduction to geology and what is known about pre-history in setting the context for his investigation. He shows that the geology, geography and climatology of the last Ice Age offer evidence that suggests there could indeed have been a land bridge — or a route for island-hoppers — to the place we dream of as Atlantis.
