C.K. Williams & Co. Quarry; Williams Quarry
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-1920s, exploiting serpentine for ornamental/building stone and tremolite as mineral pulp additives in paint and paper products. By the mid-1930s, demand for building stone diminished, but the market for its mineral-pulp carried the company until its close of operation in the mid-1940s.
Lower level quarry in serpentine/tremolite. Mineralization in the region was described as early as 1809, primitive quarrying speculated to have occurred as early as 1820. The first fully operational quarry was begun sometime in the 1830s, by Abraham Sherrer. Workings featured a working face 100 feet (ca. 30 m) by 400 feet (ca. 122 m) long. Upon Mr. Sherrer's death in 1898, an additional quarry was opened above by William B. Reed, named the Verdolite Quarry*. Both quarries eventually became part of C.K. Williams Quarry complex. These two original quarries are the original/primary sites of origin for most early mineralogical studies and specimens from the area.
In the 1950s, 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.
Note that most, if not all, 'eastonite' from this locality is, in fact, a mixture of phlogopite and serpentine. There are no modern analyses confirming the presence of eastonite in Easton; Livi and Veblen (1987) showed that “Eastonite” from Easton, Pennsylvania, is a mixture of phlogopite and a "new form of serpentine".
*Site listed separately to aid the locality search for older labelled specimens.
