Belle and Mayo Islands in Richmond, Virginia — The American South (Mid-Atlantic)
The Falls of the James
You are standing over the Historic Falls of the James, an approximately 7-mile stretch where the river drops 105 feet in elevation as it crosses the fall line in downtown Richmond.
The fall Line is a geologic term for an imaginary line marking where the hard rock core of the Piedmont Plateau gives over to the soft sediment of the Coastal Plain. The transition causes dramatic erosion, creating waterfalls and rapids on rivers crossing the zone.
The opportunity for harnessing the motion of water for power made Richmonds riverfront a natural location for early industry. Now it is beloved by whitewater paddlers who enter the Class III Pipeline rapids at a breach in the dam just below you.
Upriver, to your left, is Belle Isle, one of the city's first industrial centers.
A dam, a mill and mill race, and several iron and nail factory buildings were all constructed on the island between 1814 and 1836. Granite was quarried there in the 19th and 20th centuries, and industrial production continued until the Old Dominion Iron & Nail Works closed in 1972.
After two centuries of industrial use, the City of Richmond acquired Belle Isle for a park in 1973. The island is a centerpiece of the James River Park system with walking trails, picnic facilities, and a mountain bike skills park. It can be reached from the north shore by the suspended pedestrian bridge below the Lee Bridge.

The bridge before you is the Robert E. Lee Memorial Bridge completed in 1989. The stone piers below it are remnants of a railroad crossing that served industry on the island. In the 1986 photo above, the arches of the former Lee Bridge (completed in 1934) frame the construction of piers for the new Lee Bridge.
