Thornwood, New York in the context of "Tuckahoe marble"

Tuckahoe marble (also known as Inwood and Westchester marble) is a type of marble found in southern New York and western Connecticut in the Northeastern United States. Part of the Inwood Formation of the Manhattan Prong, it dates from the Late Cambrian to the Early Ordovician ages (~484 ma ago). It was first quarried on a large scale commercially in the village of Tuckahoe, New York. Deposits are also found in the Inwood area of Manhattan, New York City, in Eastchester, New York, and extending southward to parts of the Bronx, such as Kingsbridge, Mott Haven, Melrose and Tremont and Marble Hill (administratively part of Manhattan borough). Other locations in Westchester County include Ossining, Hastings, and Thornwood.
