This quarry was "in the southeastern part of Moose Island, three-fourths mile west-southwest of Stonington." The operator was the John L. Goss Corporation of Stonington, Maine. Granite from the quarry was a lavender-tinted medium-gray color with a coarse texture that that found at the Goss and Ryan-Parker quarries on Crotch Island.
The Moose Island Quarry opened in 1873. When the quarry was measured in 1905, it was 600 by 200 feet and had an average depth of about 17 feet. Transport of the granite was by a track 200 feet to the wharf.
Granite from the Moose Island Quarry was used in the Gate house at Central Park and the steps of Columbia University in New York; and in the trimmings of the Hampton Dormitory in Cambridge, Massachusetts.
