LOL I don't remember exactly what the story at the link indicated, but I
got the impression that it was "remains" of trees that were being looked
at.  ;)

There are some interesting things about the Great Lakes during the Ice Ages
that I have picked up over the years.  The Lake we now call Huron used to
have two outlets to the south... one may have been on the Bay there.
During or after one of the Ice Ages, the easternmost outlet got cut off or
plugged up.  This, in turn, caused the Mackinaw River to flood, which
caused the ~100-ft waterfall where it emptied into Huron to disappear under
water and forming the Straights that we know today.

I wish I remembered more about that.  I trot that one out whenever anyone
tries to claim there are "only four" Great Lakes.  ;)

That is quite true.  We never know what the alternative would be, but
assuming that the alternative is whatever we think "normal" is would be
very short-sighted... and probably make for some interesting science
fiction.
