Grave Creek Mound
One of the largest cone-shaped burial mounds in North America, about 19 metres high and 73 metres across, in Moundsville, West Virginia, on the Ohio River. People of the Adena culture moved more than 60,000 tonnes of earth to build it, about 250–150 BCE, over burials.
Amateur diggers tunnelled into it in 1838, finding skeletons with beads, sea shells and copper bracelets, but destroying much evidence. It is the largest surviving Adena mound and now has a museum.
