Gateway to Atlantis
Gateway to Atlantis  by Andrew Collins is one of the better books on the subject. It is a fully indexed and referenced work that clearly indicates the effort and depth of research that went into producing it.
Collins was originally inclined to believe that the Antarctic had been the home to Atlantis but has gradually come to focus his attention on the Caribbean. He has trawled the classical writers for any possible reference to Atlantis and has concluded that all their considerable evidence points to the Atlantic and in particular the Caribbean as the location of Atlantis.
In order to explain the sudden destruction of Atlantis, Collins discusses the possibility of some kind of cometary or asteroidal impact being the culprit. He is inclined to see the Carolina Bays as remnants of this collision. His conclusions are closely mirrored by the views of Emilio Spedicato. More details can be found on Collin’s website(a).
>Another sceptic, Paul Heinrich, has also offered a critical review of ‘Gateway’ with particular reference to geological evidence offered by Collins(c). Collins and before him Otto Muck and later Hancock viewed the Carolina Bays as evidence of a possible civilisation destroying impact. Heinrich took a different view when he concluded that “In a detailed examination of the geologic evidence offered by Collins for a catastrophic meteorite or comet impact about 10,500-10,600 BP (8,500-8.600 BC), I found that none of the observations or data provide convincing evidence for such an event. In the case of the Carolina Bays, there is overwhelming evidence that these features formed tens of thousands of years before 10,500-10,600 BP. Thus it is impossible that these features could have been formed at the time proposed by Collins.” My problem is that Heinrich’s very ancient date for the ‘bays’ raises the question of how they are not eroded to a greater extent!<
