Arnold Granite Quarry (Great Hill Quarry; Hazelton Quarry), Haddam, Middlesex Co., Connecticut, USA
The Arnold stone quarry on Great Hill started in 1794 and ended operations in the early 20th century. The southern part started as the separate Hazelton Quarry but apparently the two merged into one quarry at some point. It followed a N-S trending outcrop of near vertically-foliated biotite-garnet gneiss known in the early 19th century as the "Allen vein" (Shepard (1837), Williams (circa 1945)). The gneiss is cross-cut by numerous thin, zoned pegmatite dikes similar to those described by Barton and Goldsmith (1968) further south along the same formation on Long Hill. Minerals reported from the quarry are those occurring in both the gneiss and in the pegmatites.
According to the Haddam Historical Society web site, stone from this quarry was used to construct the 1845 Middlesex County Jail at the intersection of Jail Hill Road and the old Middlesex County turnpike (now state Route 154). "The Arnolds provided all the raw material for the jail including stone from their quarry." This building still stands and serves as a convenient place to view stone from the Allen vein.
