This quarry was "in the southeastern part of Green Island, 1 mile southeast of Stonington." The operator was Latty Bros. Granite Co. of Slatington. Granite from the quarry was reported to be a pinkish-buff color with a coarse texture. Transport of the granite was by a 100-foot track to the wharf.
The quarry was opened in the spring of 1905, although at the time of the report it was abandoned.
