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 high and 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.
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 and its base as .
Originally a moat of about in width and 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.
History
Pre-history
Grave Creek mound was created during the Woodland time period (late Adena Period around 1000 BC to about 1 AD). The people who lived in West Virginia during this time are among those groups classified as Mound Builders. This particular tumulus or burial mound was built in successive stages over a period of a hundred years.
18th century
The Grave Creek Mound was believed first seen by a European American in 1770, when Joseph Tomlinson and his brother built a log cabin at Grave Creek Flats. Joseph discovered the mound accidentally while hunting. Two years later, he built a cabin for his family from the mound. It was visited in 1775 by the young Englishman Nicholas Cresswell on his canoe expedition down the Ohio River. He describes the mound, its history and surrounding structures in his journal (p. 71). In 1803, Merriwether Lewis wrote about the mound in his journal; he saw it on his way to meet William Clark in Louisville, Kentucky on their expedition to explore the Louisiana Purchase.
