During road realignment and construction of a commercial building in the fall of 1984 through summer of 1985, a small serpentinite body and surrounding metamorphic rock was blasted. The serpentinite is one of several similar lenses mapped by Fritts (1965) as "Odl" (Ordovician Derby Hill Schist, limestone member) and paralleling the south side of Route 1 from the Baldwin Quarry in Milford NE to the Maltby Lakes in New Haven. The geology and mineralogy is essentially identical to that found at the Baldwin Quarry. No outcrops remain at the construction site, but about 150 meters NE along the strike there are exposures near some retail shops.
