Joppa Hill, Amherst, Hillsborough Co., New Hampshire, USA

The Joppa Hill prospects are in Amherst, close to the Amherst-Bedford line. A vesuvianite crystal from this locality was illustrated in the 2nd edition of Dana's System of Mineralogy (1844). Mineralization occurs in bedrock exposures of contact metamorphosed limestone and in a quartz vein, both in Amherst. Boulders extending across the town line into Bedford also produce specimens. This mineral list includes occurrences in both towns.
