Worked for soapstone ca. 1885-1895. Mined for talc beginning in 1909.

According to P.W. Brown: At the old King place nearly one mile east of the Tunnel we find a large bed of sepentine with dolomite. It is compact, even grained and in color dark gray with traces of green on the fractured or sawed surfaces. A considerable amount has been taken out of this bed for soapstone stoves and bed-warmers.

Taconian ultramafic tectonic "sliver" located on a major regional thrust fault at the top of the Rowe formation, separating it from the Moretown formation.
