Januzzi (1959) documents a hydrothermal mineral vein at "a new locality near Judd’s Bridge" that hosts sulfides and quartz in calcite, its exact location undocumented. Because Judd's Bridge is in Roxbury, but the "Judd's Bridge" kyanite locality is in Washington, it is not even certain which town it is in (assumed Washington). But it clearly has the wrong mineralogy to be at the kyanite locality. The details of the locality are found under the discussions of the various minerals found in area.
Under the discussion for galena, the most detailed, he writes:
"...a hydrothermal deposit in schist where rich masses of galena have been found associated with pyrite, pyrrhotite, sphalerite, chalcopyrite and quartz in a gangue of white calcite."
Under greenockite he says he found one specimen.
Under pyrrhotite he says he found small crystals in a variety of forms.
There are no details on chalcopyrite, pyrite, sphalerite, quartz or calcite from there.
