Inscription. Conneaut Lake is a kettle lake formed by the receding glacier during the last Ice Age, about 12,000 years ago. As the glacier melted, a large block of ice partially embedded in accumulated sediment formed the depression, which became the lake. Prehistoric Mastadon and Woolly Mammoth bones have been found preserved in the layers of silt in and around the lake, giving evidence of their existence during this period. The glacier changed the water flow from the north to south, making it a part of the Mississippi River drainage system.

Conneaut Lake is Pennsylvania's largest natural lake, four smaller kettle lakes exist in the area.
