Kettle (landform)

The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction.

[clarification needed] Kettles are fluvioglacial landforms occurring as the result of blocks of ice calving from the front of a receding glacier and becoming partially to wholly buried by glacial outwash.

[2] Kettle holes can also occur in ridge shaped deposits of loose rock fragments called till.

It was found in field observations and laboratory simulations done by Maizels in 1992 that ramparts form around the edge of kettle holes generated by jökulhlaups.

Kettle ponds that are not affected by the groundwater table will usually become dry during the warm summer months, in which case they are deemed ephemeral.

The Prairie Pothole Region extends from northern Alberta, Canada to Iowa, United States and includes thousands of small sloughs and lakes.
