A  Giant's kettle is a hole created under a glacier by a stream with the rotation of one or more stones in bedrock. If the stone is big enough and the hole deep enough when the glacier is gone, the stream can continue to dig the hole and to polish the stone. The kettle and stones are very regular, looking like eggs in a perfect round nest.
