They say the water broke out to the north rather than down the St Lawrence and Mississippi. Is that what you get from this?

[Vaquero]

Yes and that could make sense too.

"They say the water broke out to the north rather than down the St Lawrence and Mississippi. Is that what you get from this?"

Yes. They were dammed up and broken a couple times. The biggest flood went north into the Hudson Bay...the ice sheet that was on the largest lake, became boyant, broke and slid into Hudson Bay causing gawd awful tsunamis.

Once this 'chill' period was over, the Ice Age melt resumed unhindered.
It was just after this period that the Mediterranean reflooded and eventually broke the dam at the Bosporus and flooded the Black Sea.(Noah's Flood?)

These lakes were held in place by ice?
