St. Anthony Falls has long been one of Minneapolis' top attractions. But the endurance of the falls is due to some complex infrastructure designed to halt erosion. A key component of that infrastructure is a hidden wall -- buried beneath the river -- that has protected the falls for roughly 145 years. Little is known about the wall's condition, however. River historian John Anfinson believes there needs to be a comprehensive study of the structure's status. Anfinson is the former superintendent of the national park comprising the Mississippi River in the Twin Cities.
