Two small feldspar prospects in a granite pegmatite on what was the Knudsen property back in the first part of the 20th century (still on private property as of 2017). Stugard (1958) shows a small pegmatite with a quarry symbol here, but there is no written documentation on its operation. 1934 aerial photographs show light-toned disturbed areas where the prospects are located, which is not far from the Tidewater Feldspar Company mill just SE on the Connecticut River immediately west of the Rock Landing promontory. At this time, Tidewater operated the Rock Landing Quarry uphill from the Knudsen prospects and perhaps prospected this pegmatite also.
