Atlantis II Deep (l)
Atlantis II Deep is the name of the largest submarine basin in the Red Sea reaching a maximum depth of 7,160 feet where hot brine is produced at 56°C. The Red Sea is an extension of the Rift Valley and is in a tectonically active region.
Gene Matlock quotes Rajeswar Gupta(a), the Bengali historian, who states that the Red Sea and the Mediterranean had in earlier times been connected by a strait. Coincidentally, the controversial Oera Linda Book supports this contention(b).
