Horse Race, Turner's Falls, Montague

Marsh's (1867) field notes and the contemporaneous Atlas of Franklin County, Massachusetts (Beers 1871), provide a potential solution to the problem of identifying the type locality. Marsh states that the main locality he visited was on land formerly owned by Field and later sold to Stoughton. Field's land holdings along the Horse Race originally encompassed both sides of the river, but the 1871 map shows land on the south bank (containing the locality we excavated) as belonging to Stoughton. This information and the fact that abundant, articulated larvae occur in only one of the three lacustrine units currently exposed in the area strongly suggest that the type locality is contained in the middle lacustrine bed currently exposed on the south bank of the Connecticut River in the town of Montague.
