The Great Lakes Rock
From the round surf-polished rocks of Lake Superior’s shore
to the sand dunes of Lake Michigan, I have roamed and picked up stones: agates,
pudding stones and some bearing copper or fossils. And I hiked the alvars on the Door Peninsula
and Ontario’s Bruce with their layered limestone shores bearing fossils of
ancient salt seas. Lake Huron’s green
waters pour into Lake St. Clair and its silty marshes and then to Lake Erie
teeming with birds and fish. The waters pick up speed in the Niagara River to
take a tremendous plunge over Niagara Falls.
The rock underlying the falls will wear away in time I am told, but not
in my life time. Lake Ontario’s flat
shores have good soil for vineyards and farm lands. Sailors and sports fishers enjoy Lake
Ontario’s riches and the lake flows out through the St. Lawrence River with a
myriad rocky islands.
