Giant Kettles and Pot Holes
Image Description from historic lecture booklet: "Plunging and swirling water of a river drills holes in the rock. Pot-holes are also drilled by the streams which drop through wells from the top to the bottom of a glacier. Falling hundreds of fee, the streams acquire great force and are able to excavate pits of astonishing size. At Cohoes, N.Y. are several which measure from 10 to 30 feet in diameter, and these held ponds and swamps after the glacier which made them had disappeared. In clearing out the swamp much from one of these, to find firm foundation for a mill, the skeleton of a fossil elephant was discovered."
