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.
