About a thousand miles straight to the south from Tunisia, in the heart of the western Sahara desert, are the archaeological sites around an ancient lakebed called Gobero, which during the Ice Age was fed by streams from the Air mountains just to the north collected in that basin heaving been formed by a block-faulted sandstone ridge, the lake about a hundred square miles, now a sea of sand. Columbia University research professor of paleo-climatology Kevin Uno who has been studying Gobero says that area did not dry up completely until circa 1000 b. c., yet cites no reason that it happened, as with all uniformitarians not realizing that the Ice Age began to end circa 1500 b. c.
