Definitions and Scope:
Information and Mineral Sequence for Hanson/Benchmark Quarry, St. Johnsville, NY This is an active commercial crushed stone quarry. It is both illegal and dangerous to enter without permission. You risk fine and possible jail time if you enter this quarry without permission. As far as I am aware - the owners NEVER give permission.
A public service project always open to input from the community interested in Herkimer diamonds.
From a scientific point of view, when looking at the entire Herkimer district, this location should be considered a "rare historical artifact". It is a deposit that has preserved the intersection of three key mineral producing events in the region with a clarity NOT seen in any other Herkimer deposit (except as isolated pockets). This deposit is very special and it is a shame that scientific access is not being granted.
A community effort will be needed to help gather information on this very important deposit. Use the email!
Donations of specimens and photos from this deposit are needed. Please help!
