Originally a granite quarry, opened in 1880. Now a crushed stone quarry operated by Cherenzia Companies. Rocks occuring here including granite, granite-gneiss, gneiss, amphibolite, schist, pegmatite and aplite. Monchiquite dikes occur in the southeastern area of the quarry and just outside of it in road cuts on CT Route 78. These dikes are notable for containing xenolithic nodules derived from the mantle. (Hermes, 1987)
