One of the world's greatest and oldest operated iron mines, was located in Lebanon County (Pennsylvania) and lay in two deposits. One deposit outcropped and was accessed easily. The top of the second deposit lay 150 feet underground; this deposit was not located until 1919. The first deposit proved to be the most important source of ore for area iron furnaces until the late nineteenth century.
Until the mid-nineteenth century, the workers used pick axes and pry bars to dig ore out of the ground. With the construction of the railroad for the transportation of the ore, mining techniques changed. During the 1870's steam shovels replaced hand-loading of railcars. By the late nineteenth century the Lebanon County ore mine developed into the largest, most important iron mine east of the Lake Superior ore deposit.
In 1926 mining began in the second ore deposit, and a steel corporation gained sole ownership of both deposits to supply ore to its steel mills. Mining continued until 1973 when Tropical Storm Agnes filled the mine with water. The value of the remaining ore was not worth the cost of draining the mine. After 234 years of operation and total production of 106 million tons of ore, the Lebanon County ore mine closed down.
