Etna Township Mounds

The Etna Township Mounds are a pair of Native American mounds in Etna Township, Licking County, Ohio, United States. Located east of Reynoldsburg near Interstate 70, the mounds are built primarily of sand. Unlike typical Native American mounds, their location reveals nothing of their builders: they are not built atop hills or along a stream, as Adena mounds typically are.

Because the mounds have never been archaeologically excavated, virtually nothing is certain about them other than that they were constructed by one of the mound-building cultures that inhabited Ohio during the Woodland period.

It has been proposed that the mounds are the work of a group of individuals isolated from the rest of their culture. Because excavation of the mounds is likely to yield valuable information about such isolated groups, the mounds are a potential archaeological site. In recognition of their archaeological value, the Etna Township Mounds were listed on the National Register of Historic Places in 1975.
