Graves at the site are composed of bodies contained within limestone stone box graves. A cemetery of this type from the Fort Ancient period is very uncommon, making the Stone Graves a valuable archaeological site.:1373 Increasing the significance of the area is a complex of other nearby Fort Ancient sites, including the Bone Mound II that is only 500 feet (150 m) away. Because most Fort Ancient sites include only a single type of burials, rather than both a mound and a cemetery, it is believed that the vicinity of the Stone Graves may have been inhabited by people of two different foci.:1372 In the future, more information may be gained from the cemetery, for the site has never been subject to an archaeological excavation.:1373
On July 15, 1974, the Bone Stone Graves were listed on the National Register of Historic Places because of their archaeological value. The Bone Mound II was listed on the Register on the same day.
