On the little plateau east and below the site of Fort Neilson, near the
center of the American line, is located a reconstructed stone powder
magazine. From the report of Ebenezer Stevens, Major Commandant of
Artillery, entitled, "Return of Ordnance and Stores in Camp near
Stillwater, September 24, 1777," with a subheading, "Stores in
Magazine," it has been possible to determine the exact character and
quantity of the supplies located within the magazine.
