I was looking for something on that and found that 10,500 years ago
during the ice there were 2 huge lakes in this area, Lake Duluth
and Lake Algonquin (were there people who named them back then??)
and they were somewhat torn apart as the ice receded and eventually
became what we know today..  Lakes Superior, Michigan and Huron..

There was another big one called Lake Iroquois that got a lot smaller
and became the widest part of the St. Lawerence too. And back just
after the ice started receding, those lakes drained North, not South,
because the thicker ice further North had compacted the earth more
so it was down hill in that direction for a few thousand years..

Yes, and in general, these sorts of things don't happen on a schedule
and other events will mostly just make the warming or cooling happen
a little sooner or later than estimated, but in the calendar of the
world, a 'little late' could be a few thousand years..

But, as I've mentioned before, they know that the world has had
twice as many years with no polar ice caps at all than with them
so assuming we are getting unusually warm right now may not be
tchnically correct. We just have gottn used to the Cold..
(As Canadians, that's something we understand..)   B)
