The Grave Creek Mound in the Ohio River Valley in West Virginia is one of the largest conical-type burial mounds in the United States, now standing 62 feet (19 m) high and 240 feet (73 m) in diameter. The builders of the site, members of the Adena culture, moved more than 60,000 tons of dirt to create it about 250–150 BC.

Present-day Moundsville has developed around it near the banks of the Ohio River. The first recorded excavation of the mound took place in 1838, and was conducted by local amateurs Abelard Tomlinson and Thomas Biggs. The largest surviving mound among those built by the Adena, this was designated a National Historic Landmark in the mid-20th century.
In 1978 the state opened the Delf Norona Museum at the site. It displays numerous artifacts and interprets the ancient Adena Culture. In 2010, under an agreement with the state, the US Army Corps of Engineers gave nearly 450,000 artifacts to the museum for archival storage. These were recovered in archeological excavations at the site of the Marmet Lock, and represent 10,000 years of indigenous habitation in the area.
