Some Amazonian Native Americans descend partly from a Native American founding population that carried ancestry more closely related to indigenous Au… - Graham Hancock

Traditions, with all their folksy redolences, are relatively safe matters for scholars to speculate about. Maps and nautical charts on the other hand — especially accurate, sophisticated maps of the kind used by Guzarate to chart Vasco da Gama's course from Malindi to Calicut in 1498 — are quite another matter. If maps have indeed come down to us containing recognizable representations of Ice Age topography — as arguably may be the case with the depictions of India and of the long-submerged Sundaland peninsula by Cantino and Reinal and with the depiction of the 'Golden Chersonese' by Ptolemy — then prehistory cannot be as it has hitherto been presented to us.
If they are what they seem, such maps mean a lost civilization. Nothing more. Nothing less.

If the Edfu Texts contain a record of these events, as I have proposed, then we should take seriously the message they transmit, that there were survivors of the cataclysm who made it their mission to bring about: 'The resurrection of the former world of the gods. ... The re-creation of a destroyed world.'
These survivors are said to have wandered the earth, setting out and building sacred mounds wherever they went, and teaching the fundamentals of civilization, including religion, agriculture, and architecture.

A 24,000-year sequence recorded in a marine core from the Santa Barbara Basin, off the coast of California, exhibits the highest peak in biomass burning precisely at the onset of the Younger Dryas. ... This anomalously high peak correlates with intense biomass burning documented from the nearby Channel Islands. ... The peak also coincides with the extinction of pygmy mammoths on the islands and with the beginning of an apparent 600-800-year gap in the archaeological record, suggesting a sudden collapse in island human populations.
