It is said that some of the Great Lakes
were part of a tropical ocean in the past (see below picture). There are geological proofs to this as seashells
of that age formed the limestone and dolomite rocks of the Niagara Escarpment
. Well, if there are seashells then there is the possibility to find pearls
. I found recently a treasure place
, not too far from Niagara, with lots of seashells
that produce pearls
. We can think the place itself as a pearl.
