Quarry in serpentine/tremolite, located on Chestnut Hill, above the Delaware River, North of Easton. Owned by the C.K. Williams & Co., Easton, PA. Encompassing the original sites of the Sherrer, Verdolite, and minor workings of the Fox quarries, this site was greatly expanded in the mid 1920's, exploiting Serpentine for ornamental/building stone and Tremolite as mineral pulp additives in paint and paper products. By the mid 1930's, demand for building stone diminished, but the market for it's mineral-pulp carried the company until it's close of operation in the mid 1940's.
In the 1950's the property was put up for sale and purchased by famed Mineralogist Arthur Montgomery, at that time an acting professor at Lafayette College in Easton. He deeded the property to Lafayette in 1953, for the purpose of preserving this unique mineralogical site in perpetuity.
