Sierra de Alhamilla
Sandra Fernandez is a Spanish researcher who has opted for Almería in southeast Spain as the location of Atlantis. She identifies the plain south of the Sierra de Alhamilla as the plain referred to by Plato. Her website has a number of blogs devoted to Atlantis(a). Unfortunately, the site is in Spanish and I find that Google translator does not give a clear translation. Fernandez sees the Los Millares culture centred north west of Almería as preceding the Atlanteans.
I note that at the eastern end of the Gulf of Almería there is Cabo de Gata, while inland to the west of the plain lies Gádor, both of which might be variations of Gades!
