Two prospects in small, massive quartz deposits, similar to the well-known so-called "Judd's Bridge" kyanite-hosting quartz mass along the power lines nearby. These 3 masses where likely all worked for quartz at the same time, well before 1931, when Schairer mentions the "Judd's Bridge" site. There are many ~1 to 5 m thick quartz masses in the host Ratlum Mountain and Rowe Schists throughout the Washington/Litchfield/Roxbury/Bridgewater/western Southbury area that commonly host euhedral kyanite, ilmenite, fluorapatite crystals with chlorite along their contacts. The dumps for these two prospects show minor amounts of such mineralization and they do not appear in any rock-hounding guides or locality summaries.
There is no known documention on the history of these prospects, but quartz mining and milling at a few locations in western Connecticut is mentioned by Bastin in an obscure 1908 publication full of errors. This activity apparently ended in the 1920s and was soon forgotten.
Coordinates are for the western prospect, the eastern one is situated 30 m to the SE.
