5048Re: [Precolumbian_Inscriptions] Re: The Last Inland Sea
- Feb 2, 2005THe ice dams,which contained the numerous glacial lakes were breeched at various times throughout the latter stages of the last glacial maximum [23000-16000bce] and the Younger Dryas [ended circa 9600bce].There were at least three that broadly coincided with Lake Ontario.One cascaded down the Mississippi and the other two debouched along the Hudson and St Lawerence Rivers.Have not sighted many articles on lakes on the western praires of Canada,but your suspicion that there was more than one glacial lake in that region is probably well founded.Where the eastern and western icesheets merged would have been an extremely active and fluid area,when the ice melted.
