On August 6, 1918, a dumping scow with two men aboard broke loose from its towing tug and became lodged in the rapids of the upper Niagara River. A unique artifact of Niagara Falls history, the wreckage has remained just above the brink of the falls for over a century.

The vessel famously lodged just above the Horseshoe Falls is the Niagara Scow, also known as the "Iron Scow." In August 1918, the barge broke loose from its tugboat with two men aboard, Gustav Lofberg and Frank Harris. To save themselves, they opened the bottom dumping doors, causing the scow to ground itself on a rock shoal roughly 600 meters from the brink. The men were heroically rescued via a breeches buoy the next day. For over a century, the scow remained remarkably stationary until a severe storm on October 31, 2019, caused it to shift significantly and flip on its side. In 2026, it remains a high-value historic landmark, though it continues to break apart slowly due to the relentless power of the rapids, serving as a reminder of the river's treacherous nature.
