Molybdenite locality, Essex, Middlesex Co., Connecticut, USA

Silliman (1819) states: "It is found about half a mile to the E. of the Turnpike leading from Saybrook to Middletown, on the first road on the right hand above the turnpike gate, near the house of the widow Pratt. It is not far from the Pettipaug meeting-house, in a northern direction." Robinson (1825) states that it is "in a vein of quartz traversing gneiss". This may put it on River Road on the south side of Millstone Hill, which is underlain by the gray, Proterozoic New London and Rope Ferry Gneisses.

At that time, the town of Saybrook included Pettipaug (also known as Pettypaug or Potopaug until 1854, when the name was changed to Essex, which had also became a separate town in 1852) as well as the later towns of Chester (1836), Westbrook (1840), and Old Saybrook (1854). The remainder of Saybrook town changed its name to Deep River in 1947 to match the name of the major village within its boundaries.
