The eastern Adirondack Mountains in upstate New York were heavily mined for iron in the 1800s and 1900s and played an important role in industrialization of the Northeast prior to and during World War II. The mining activities resulted in piles of waste rock and mill tailings (the residuals of ore processing) in various areas throughout the region.
