Just off the path, in an area of Inwood Hill Park known as “The Clove,” are a series of rock formations that have fascinated geologists and hikers for generations.
These glacial potholes, which look almost man-made, are the product of glacial runoff that occurred during the last ice age some 50,000 years ago. During a huge melting event “turbulent, rock-fortified swirling water making its way through crevasses reached the underlying bedrock and drilled the holes.” (A Natural History of New York City’s Parks, Linnaean Society of New York, 2007)
Fun Fact: The murder mystery “The Dragon Murder Case” by S.S. Van Dine takes place in a fictionalized version of Inwood Hill. In the book the potholes were said to be the hiding place of murderous dragons.
