A moulin is a pan-shaped glacial depression that develops on a fluvioglacial plain or along both sides of a kame. The fluvioglacial deposits and the permanent ice buried inside a kame melt when the climate becomes warmer. Moulins form due to the collapse of the cover materials or glacial erosion. Moulins are nearly round in map view, and the diameters can range from a few metres to dozens of metres. They are only a few metres high. When moulins are arranged in a row, they are called a moulin chain. Based on their shape and scale, they can be divided into disc-shaped potholes, pot-shaped potholes and tub-shaped potholes.
