Graham Hancock on history: what the evidence says · JRE #1284
SUBJECT: HISTORY
The short answer
Hancock claims there is live archaeological disagreement over Serpent Mound's age, with one camp dating it to only 1,000 years old (Fort Ancient culture) versus his preferred, older Adena-culture attribution. Serpent Mound's age has been the subject of a genuine, unresolved scholarly dispute between two archaeological camps, matching Hancock's description.
Not a true/false call. Every claim is logged with its sources; read the exhibits below.
there have been arguments that there is a group of archaeologists who would like it to be just 1,000 years old, and they attribute it to a culture called the Fort Ancient culture. There's another group of archaeologists
What the evidence says 01 / RECORD
Serpent Mound's age has been the subject of a genuine, unresolved scholarly dispute between two archaeological camps, matching Hancock's description. A 1991 site excavation used radiocarbon dating on charcoal samples to determine the mound was approximately 900-1000 years old, attributing construction to the Fort Ancient culture (A.D. 1000-1500). In 2014, a different team of archaeologists presented new radiocarbon dates arguing the mound was instead built roughly 2,300 years earlier by the Adena (Hopewell) culture, with the Fort Ancient-era material reflecting later remodeling rather than original construction. As of a 2019 summary of the literature, the dispute remained unresolved, with future work expected to clarify the mound's true age. This confirms both halves of Hancock's claim: a Fort Ancient camp favoring a ~1,000-year age, and an opposing camp (which Hancock aligns with) favoring an older, Adena-era origin.
