Kettle Lakes in the U.S.: Yes, They’re Common

Kettle lakes—depressions left by melting glacial ice blocks—are widespread across the northern U.S. (Minnesota, Wisconsin, Michigan, New York, New England) and Canada. Famous examples: Walden Pond (MA), Lake Geneva (WI), and thousands in the “Land of 10,000 Lakes.” They’re a hallmark of the Laurentide Ice Sheet’s retreat.
