Rock formation in Manhattan, New York

Rat Rock, also known as Umpire Rock, is an outcrop of Manhattan schist which protrudes from the bedrock in Central Park, Manhattan, New York City. It is named after the rats that used to swarm there at night. It is located near the southwest corner of the park, south of the Heckscher Ballfields near the alignments of 62nd Street and Seventh Avenue. It measures 55 feet (17 m) wide and 15 feet (4.6 m) tall with different east, west, and north faces, each of which present differing climbing challenges. The rock has striations caused by glaciation.
