Robert Thorson - Beyond Walden: The Hidden History of America's Kettle Lakes and Ponds
Lakes are a beloved part of the American landscape, and kettles are the most common type, spanning the northern part of the country from New England to the High Plains. Kettle lakes are depressions formed by meltdown of glacial ice and filled with freshwater. Unlike other kinds of lakes that have significant inlet or outlet streams, kettle lakes are natural wells tapping the groundwater table.
