A small quarry in a serpentinite body near the north end of the northern Maltby Lake. It appears to have originally been dunnite caught up in continental collision and included within the Ordovician Malty Lake metamorphic rocks in the Orange-Milford Terrane. It was quarried in the 1810s by Benjamin Silliman, later of Yale College mineralogy fame, but the rocks did not stand up to weathering well. Before 1822, when West Haven was subdivided from New Haven and became part of Orange, the locality was referenced as being in New Haven.
Dana (1891) says the outcrop was known as the "Serpentine Crag" and that banded, yellow-green, variegated with yellowish white and black (from magnetite) slabs were polished and placed in the Yale College cabinet. Chrysotile and diopside were also noted.
