Falling Creek Ironworks was the first iron production facility in North America. It was established by the Virginia Company of London in Henrico Cittie (sic) on Falling Creek near its confluence with the James River. It was short-lived due to an attack by Native Americans in 1622.The long-lost site was rediscovered in the early 21st century. It is now located in Chesterfield County, about 5mi south of the fall line of the James River at present-day Richmond, Virginia. Archaeological and related research work at the site was ongoing as of March 2007.GeographyThe geology of Virginia's terrain changes from the sandy coastal plain of the Tidewater Region to the more hilly and rocky Piedmont Region along the north-south fall line. At Richmond, the generally west to east flowing James River turns almost due south and essentially flows parallel to and just east of the fall line for about 8mi, before turning east again near Drewry's Bluff. On the west bank of this section, the Piedmont terrain contained the ore deposits needed to make iron, but was still adjacent to the navigable portion of the James River through the Tidewater Region. A local tributary, Falling Creek, flowed downhill into the James River, providing the water power needed.
