Drumlins have shapes like overturned canoes. Kettles are formed when a big chunk of ice separates from the main glacier. This chunk is surrounded by rocks and dirt that the glacier leaves behind. When the chunk of ice melts, it leaves a deep hole. Today, kettles are usually filled with water and look like a lake or a pond.
Eskers are long, winding, narrow hills.
They are formed by meltwater streams within glaciers. Overtime, deposits in the streams build up. They become long snakelike hills that follow the shape of the stream. Sedimentary rock, horizontally bedded. All rights reserved.
