Cold Spring, NY: West Point Foundry
West Point Foundry Cove marsh was remediated (cleaned and restored) by the EPA and private industry as a National Priority Superfund Site (Marathon Battery) in the 1990s. The factory had released cadmium and nickel into the environment in the production of batteries for NIKE missiles, it was reported. The historic West Point Foundry was in the small valley to the north and east.
This is the approximate end of a large dock which had two railroads tracks on it that cross-looped (“frogs”) at its end near the marker. Was it used to load and unload ordnance that was not shipped on the mainline? There is a map in the Foundry School Museum nearby. While working there for the EPA, we witnessed its apparent demise, by fire, when a reported waterspout that winter temporarily lowered the Hudson River, exposing the tops of burned pilings all the way out to the marker, which is placed based on map and the visual emergence anomaly seen in these photos. Nearby land-filled peninsula is not the remains of the historic rail-head but a more modern one, for the Chicago Bridge and Steel Co., which ended around the end of 1912.

What was recovered from the archaeology of Foundry Cove, along with other features connected with the “iron age”, was the wooden platform and gun carriage pintle as depicted in the document photo below: the so-called “Swamp Angel” after it exploded bombarding Charleston in 1863. The State of South Carolina has yet to find any remains of the man-made island in the swamp but a marker is where it probably was.

and the Wikipedia entry on the Parrott rifle (“Swamp Angel” section) and you will see there seems to be a disagreement on the facts of that event in 1863 in the number of shells before the gun became inoperable. It also explains that it was the “First” so the Library of Congress photos are of other(s) that followed.
