Note, the entrance road to this quarry is on State Route 67 in Southbury, however the quarry starts about 0.5 mile north of the entrance road and the vast majority of it is mostly in Woodbury. Because O & G operates another quarry farther north in Woodbury (O & G No. 1 or the "Woodbury" Quarry), this locality has almost universally been referred to as the "Southbury" Quarry to differentiate it, even though it too is technically in Woodbury.
Well known Connecticut locality for prehnite.
