Dr. Robert F. Schmalz (1929- ), a geologist with Pennsylvania State University, declared his support for a Tunisian-Algerian location for Atlantis, which included northern Tunisia and part of northeastern Algeria. He describes how just northeast of Gabes there is a low sandy plain which separates the Mediterranean from the salty chotts that extend hundreds of miles westward into the Sahara.
In the article in the Montreal Gazette of 26/8/77(a), he cities dramatic changes in sea levels and land elevations as the cause of its destruction. He dates this event to the end of the last Ice Age conforming closely to the prima facie date given by Plato for the time of Atlantis!
His ideas, among others, were reviewed by the geographer Richard B. Cathcart in a 2001 paper(b).
