Iron Mine Pond
Taconic State Park
According to legend, Caleb Maltby, an ardent Republican, closed the mine in 1884 because a Democrat, Grover Cleveland, was elected president. The Thomas Iron Company continued to work the mine , but not the furnace, until 1893. After the mine closed, the ore bed filled with groundwater; it is now known as Iron Mine Pond.
How Maltby’s Mine Worked To convert the raw ore into iron required large quantities of charcoal. The charcoal was supplied by “colliers” from local pits. The furnace was filled with a layer of charcoal, a layer of limestone, and a layer of iron ore. The limestone acted as a purifying agent in the process. After the mixture was ignited, the layers settled and more charcoal limestone, and iron were added. Molten iron was then drawn off and cast into iron ingots.
Bottom left: At first, Maltby’s Iron Works obtained hardwood charcoal from local pits. As these sources were exhausted, the charcoal was brought in by rail from further away. This photograph shows Maltby’s Iron Works charcoal kilns in Berlin, New York, which operated in the 1870s and 1880s.
Bottom right: The Maltby Iron Company used pumps to keep water from filling in the ore bed. Once iron production ceased in 1893, the ore bed filled with water, and an ice house and ice elevator were built. Ice was harvested on Iron Mine Pond using similar methods to those shown in this historic photograph from nearby Rudd Pond.

From 1861-1884, the Maltby Iron Company’s mine and furnace produced an average of 100 tons of iron per week. Several dozen men worked for the company, alternating 12-hour shifts to keep the furnace in producton eight or nine months a year.
