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.

Description

Grave Creek Mound is the largest conical type of any of the mound builder structures. Construction of the earthwork mound took place in successive stages from about 250–150 B.C., as indicated by the multiple burials at different levels within the structures. In 1838, road engineers measured its height at 69 feet (21 m) and its base as 292 feet (89 m).

Originally a moat of about 40 feet (12 m) in width and five feet (1.5 m) in depth, with one causeway across it, encircled the mound for defensive purposes. Inside the mound, archaeological researchers have discovered Adena remains and ornaments. In addition, they discovered a small sandstone tablet, the Grave Creek Stone, which modern scholars believe to be a hoax.
