The Reservoir Stone Mound (33LI20) located in southeastern Licking County, Ohio, originally was between 12 and 15 m (40 and 50 ft.) high. It was the largest aboriginal stone structure north of Mexico. A fragment of wood from a unique wooden burial platform excavated from the mound in 1860 has yielded a radiocarbon date of between cal A.D. 85 and 135 situating it in the early Middle Woodland period. Artifacts reportedly found in association with the burial platform suggest an Adena cultural affiliation for the mound.
