NOTE: This is not a mineral occurrence location. It is a spillage site from a historic ore loading operation. The actual occurrence is 4 miles to the west of this location. Happy hunting!!

The historic dock where the magnetite ore was loaded into barges on the Hudson River, mainly from the Forest of Dean Mine, 4 miles west of of Fort Montgomery, famous for its high-quality magnetite ore. The mine and dock operated between 1756 and 1931, producing over 2 million tons of ore. The ore was crushed to a uniform size at the mine site, and then moved to the dock. From the beginning, ore was brought to the mine dock by horse-drawn wagons. In 1906, an aerial tramway was constructed to cut down on travel time between the mine and the dock. Historic photos at a local museum show aerial tramways bringing half-ton buckets of iron ore to the river's edge to be dumped and loaded into a 1,000 ton storage bin, and then into waiting wooden barges, or into rail cars, to be brought to the smelter in Secaucus, New Jersey to be processed.

Unique to this site is the magnetite iron ore found along the River Bank on the north end of the park, near the remnants of the sunken barge,(see photo above) that contains calcite that has been weathered away from being in the river for many decades, giving the rocks a 3-dimensional look. The ore from the Forest of Dean Mine is noted for the magnetite-calcite mixture. The outlying ore body is a hornblende granite & serpentine granite gneiss, samples of which can also be found at this site. Specimens found at this site are from ore that spilled out during the loading processes over the 150+ years of operation.

This location is now a public park, maintained by Scenic Hudson. Park in lot, and walk across the CSX Railroad tracks, and head north (left). Look for rocks along the water's edge, especially at low tide, near the remnants of the old wooden ore barge.
