During the Ice Age, the Tamanrasset river flowed from the Ahaggar mountains of southern Algeria to the west for almost a thousand miles into the Atlantic at Cerne, that river which today would be the 12th largest river in the world, and from the Ahaggar mountains flowed to the north the Igharghar river into the vast basin now called the Great Eastern Erg (a sea of sand dunes) of northeastern Algeria where Jason and the Argounauts were blown off course from the sea at the Gulf of Gabes into the lake Tritonis system which by that time circa 1350 b. c. was already much diminished.
