A soapstone quarry about which apparently almost nothing is written except this brief description by Gates and Christensen (1975):

An abandoned soapstone quarry, about 250 feet long and between 50 and 100 feet wide, is located approximately 1/2 mile north of Soapstone Hill Road. The rock here, now completely quarried out, was an altered ultrabasic in a kyanite-bearing schist of the Hartland Formation (unit II) [now known as the Ratlum Mountain Schist].


And field trip stop description in Merguerian (1985):

The excavation, which is oriented parallel to S2 in the bounding muscovite-chlorite schist, produced commercial quantities of soapstone. Blocks from the tailings pile include talc-tremolite schist, chlorite schist, and very-coarse grained amphibolite rich in opaque minerals.

The quarry is on-strike with mylonitic amphibolite to the south. The elongate shape parallel to S2 and foliated nature of the altered serpentinite body suggests that the soapstone-talc body represents ultramafic rock deformed during D2 and possibly D1. It may mark a syntectonic ultramafic intrusion (Gates and Christensen 1965) or a small sliver of ophiolite.
