The larger Wright Mound measured 180 feet in diameter and stood 30 feet tall. Like many Adena mounds, groups built the mound where several paired-post enclosures had once stood. Ritual activities would have taken place within those enclosures. There was no evidence that the enclosure builders wove smaller saplings between the posts to form a solid wall. Thus, these enclosures may have looked more like standing screens than walled structures.
After an enclosure's last use, Adena groups often covered it with an earthen mound. In the case of the larger Wright Mound, they built a log tomb for a single individual, then covered the enclosure with soil. Each new construction phase coincided with the placement of additional burials in the mound. Of the 21 individuals buried in this mound, 14 were buried in log tombs.
Archaeologists recovered a large number of intentionally broken ceramic vessels In the deposits between construction phases. This led them to suggest that groups of Adena people had periodically revisited the mound to reconnect with their relatives. During these visits, they may have held ritual feasts that concluded with breaking ceramic vessels.
The smaller Wright Mound was 60 feet in diameter, but 50 feet tall. As with the larger mound, it was built over a circular paired-post enclosure. But unlike the larger mound, this mound was constructed in just one phase, and only two people were interred within it. A single-phase construction, coupled with just a few graves, suggested that Adena groups has used this mound for a shorter period, in comparison to the larger mound.
