A kettle is a depression or basin in the glacial drift formed by the ablation (melting) of a glacial ice block which was wholly or partly buried. These forms may have any shape in plan, although most tend to be somewhat circular equidimensional, and vary in depth from less than 8 meters to greater than 45 meters.
If deposition of sediment does not fill a kettle, a kettle lake will form from the accumulation of water.
