The quarry at Upper New Street is over 100 years old (it opened in 1893). During the mid 1980's to early 1990's, there was a lot of collecting that took place between the Upper New Street and Lower Street Quarries in an area that is referred to by some as "Middle New Street." The majority of the specimens from this area are still labeled as being found at Upper New Street even though they were not found in the quarry itself. Nonetheless, this is one of the most famous Trap Rock quarries in New Jersey and is probably most famous for its amazing and unique Prehnite casts after Anhydrite (sometimes called "fingers" or "snakeheads"). This specimen does not feature any casts, but rather beautiful bright apple green spherical aggregates Prehnite associated with Calcite on basalt matrix. This specimen is actually from a recent find, and has some of the finest color (it's more green in person than the photos indicate) Prehnite that you'll see from any quarry in New Jersey. Ex. Brian Kosnar Collection.
