The Work of Ice Age Glaciers

Pictured are glacial grooves on Kelley's Island in Lake Erie.  This is the work of Ice Age glaciers.  Here is a quote from my book, the Dynamic Great Lakes:

The glaciers ground softer rocks into smaller and smaller pieces.

The underside of the glacier picked up sharp pieces of stone and

rasped them across the earth. The glacier rasped polished grooves in

hard rock along Lake Superior’s northern shore and other places

such as Kelley’s Island in Lake Erie.

Some Ice Age glaciers remain in northern Canada and Greenland.  The Dynamic Great Lakes is available at Barnes & Noble, Amazon.com and many other online stores and fine bookstores.

Lake Erie's Ohio Shore and Islands

There is an archipelago of islands on the western end of Lake Erie:  South Bass Island, Middle Bass Island, North Bass Isand, Pelee Island and Kelleys Island.  On the North side of Kelleys Island, great grooves left by the last glacier are scoured deep into the limestone.  A trough 400 feet long and thirty five feet wide shows the direction of the glacier as it moved forward.

Fishing boats troll for warm water species of fish such as bass, walleye and yellow perch around these islands and elsewhere on Lake Erie.  Lake Erie is the shallowest of the Great Lakes and holds good fishing for these species.
