This cache is behind the woodyard of the nearby paper mill and offers a fantastic view of the old lime and marble mine. Mining in this area pre-dates the paper mill and a nearby mine was the source of New York's contribution to the Washington Monument!
Black Marble Works
The Glens Falls black marble works were located on land directly behind the paper mill main office. It is known that black marble was being mined on the site before 1865. How long it was mined before then is not known, but the mining ended in November of 1923. The actual quarrying ended about two years before. The Glens Falls mine was the only documented black marble mine in the United States at that time and is one of the hardest marble types in existence. There are many samples of the marble in the older homes of Glens Falls since it was used for fireplace mantels.
Black marble from this site in Glens Falls was contributed to the building of the Washington Monument in Washington D.C. as New York State’s official donation. The marble is located at the 160 foot landing of the monument and is inscribed with, “New York – Excelsior”. It was received and installed in 1886. Historians of the day confirmed that the marble came from the quarry very near to this cache.
