Looking at a map in Sapbush Run, it appears that there was a turntable in Boonville, which was the northern terminus for the Black River and Utica (then Utica and Black River in 1859) Between 1855 and 1867. The tracks started being extended north in 1867 and reached Clayton in 1873. The map shows a circle on a track leading to the enginehouse...would make sense that a turntable was located here. Definitely Historic.
