A burial mound stood on the platform; postholes suggest a possible henge. Biggs, Greenup, KY, has a comparable ring-ditch-and-mound layout. Grave Creek preserves an original ring ditch. At Wolf Plains, Athens, OH—22 mounds, 10 ring ditches and 40-ft Harmar Mound—the video reports additional LiDAR finds. 🏺

Key facts
- Mount Horeb's roughly 300-ft measurement applies to the smaller inner enclosure as a whole; the embankment itself is 13 ft wide.
- Inside the embankment is a 45-ft-wide, 8-ft-deep ditch surrounding a 105-ft-diameter circular platform, reached by a 33-ft-wide causeway on the western side.
- A burial mound stood on the platform. Postholes indicate a possible henge, but they do not establish that it was a woodhenge.
- Biggs Site in Greenup, Kentucky, has a comparable Adena ring-ditch and central burial-mound layout, although “almost identical” overstates the comparison.
- Grave Creek Mound preserves evidence of an original ring ditch.
- The Wolf Plains Group in Athens, Ohio, includes 22 Adena burial mounds and 10 ring ditches; Harmar Mound is about 40 ft tall. The video reports that recent LiDAR scans found additional ring ditches.
