Glacial geologic feature, formed when a block of stagnant ice from a receding glacier becomes isolated and buried in glacial outwash or drift before it finally melts. When the block disappears, it leaves a pit or depression called a kettle, in the drift. These depressions range from 15 ft/5 m to 8 mi/13 km in diameter, and some exceed 100 ft/33 m in depth.
As time passes, water sometimes fills the kettles to form lakes or swamps, features found throughout much of N North America. Lake Ronkonkoma, the largest lake on Long Island, New York, is an example. + prikaži više
