A word about abandoned mines!
Many of the environments presented on this website are perilous and were only accessed with a thorough understanding of the hazards present and the necessary precautions to mitigate them. This often involves engaging the expertise of professional miners or underground search and rescue teams who possess a comprehensive understanding of the abandoned workings, airflow patterns, and specific hazards inherent to a particular location. Never enter an abandoned mine without the appropriate training, people, equipment, and protocols in place.
It is important to note that mines were not constructed with longevity in mind and many that were built over a century ago now present a plethora of hazards such as unstable rock formations, deteriorated timber supports and ladders, unexpected drops, and the potential for sudden roof collapses. Additionally, the presence of invisible and flammable gasses or lack of oxygen, heighten the risk of injury or death. In coal mines, the presence of methane and black damp must be taken into careful consideration. Furthermore, barometric changes above ground can cause shifts in airflow underground which can trap individuals in areas with poor air quality, making escape impossible.
STAY OUT AND STAY ALIVE!


Steam Hoisting Engine and Ore Cart - Abandoned Coal Mine - Pennsylvania

Carbide lamp - Photographed from the collection of The Lackawanna Historical Society. These early miner’s lamps had an exposed flame which could ignite flammable gases that collected in mines, causing explosions.

Permissible Safety Lamp - Permissible lamps were designed to operate in air that may contain coal dust or gases, both of which are potentially flammable or explosive. Open flame lamps could ignite flammable gases which collected in mines, causing explosions; safety lamps were developed to enclose the flame and prevent it from igniting the surrounding atmosphere.




One of very few surving structures in the once thriving coal mining town that has suffered from an undground coal mine fire since since 1962 and continues to burn to this day.

The Splitrock Iron Furnace
Located in Morris County, New Jersey, it was built in 1862 during the height of the American Civil War. The furnace was constructed by the Split Rock Iron Company, which was formed by a group of local investors who saw the potential for iron production in the area. The furnace was built near a large deposit of iron ore and was powered by a nearby stream, which provided the necessary water to power the furnace's blast machinery.
Splitrock Furnace #4 - New Jersey - 1862
During its peak production years, the furnace produced over 400 tons of iron per month and employed over 200 workers. The iron produced by the furnace was used for a variety of purposes, including the production of weapons and ammunition for the Union army during the Civil War. The furnace also produced iron for other industrial uses such as railroads, bridges, and buildings. However, after the end of the war, demand for iron dropped significantly, and the Splitrock Iron Furnace was forced to close in 1866.

The Oxford Iron Furnace
Represents the early development of the iron industry in the United States during the 18th and 19th centuries. The furnace was built in 1741 and was in operation until 1884, producing iron for various purposes such as weapons, tools, and machinery. The furnace is notable for its use of charcoal as a fuel source, which was the primary fuel used in iron production during the colonial period. The furnace also utilized a blast mechanism, which was a significant technological advancement at the time, that increased the efficiency of the iron production process.The Oxford Iron Furnace also played a crucial role in the American Revolutionary War, as it supplied iron for weapons and ammunition used by the Continental Army. Additionally, the furnace was operated by skilled ironworkers, many of whom were enslaved Africans, highlighting the important role that enslaved labor played in the early American economy.

The Scranton Iron Furnace
A key site in the development of the iron and steel industry in the United States during the 19th century. The furnace was one of the largest and most productive iron furnaces in the country during its period of operation. The Scranton Iron Furnace played a crucial role in the growth of the iron and steel industry in the region, providing the raw materials needed for the construction of infrastructure, such as bridges and railroads, that helped to spur economic growth and industrialization.The Scranton Iron Furnace also represents an important period in the history of American labor, as it was one of the first sites to employ a large number of immigrant workers from Ireland and other countries. These workers faced difficult working conditions and low wages, but their efforts helped to lay the foundation for the growth of the American middle class. The Scranton Iron Furnace is now a historic site, preserved as a monument to the country's industrial heritage, and serves as a reminder of the sacrifices and contributions of the workers who helped to build the United States into the industrial powerhouse it is today.

The West Point Iron Foundry
Represents the early development of iron production in the United States during the 19th century. It was the first government-owned iron foundry in the country and played a crucial role in the country's industrialization and economic growth.
Established in 1818 and in operation until 1911, it produced iron castings for various purposes such as weapons, tools, and machinery including some of America’s first steam engines, locomotives, pipes for New York City’s water system and cannons that helped win the Civil War. It also produced a wide range of iron products for civilian use, including engines, boilers, and other machinery.
In 2021, the West Point Foundry Archeological Site, which includes foundry remains and nearby Foundry Dock Park, was designated a National Historic Landmark, the federal government’s highest recognition for places that increase understanding of America’s past.

The Atlantic Avenue Tunnel

Created to connect the Long Island Rail Road (LIRR) to the rest of the rail system in Brooklyn. The tunnel was originally built in the 1840s as a means of transporting goods and passengers from the LIRR to the rest of Brooklyn, and was intended to bypass the congested surface streets of the city. The tunnel was also used by streetcars and subways, which operated in the tunnel until 1861. The tunnel was closed to subway service at that time and has been unused since then.
This was the last photo taken before the city shut down access to the tunnel in 2010.
