 | | Moreover, though the Serpent Mound acropolis is not as extensive as Iowa's Effigy Mounds, taken as a single mound it far exceeds even the massive Great Bear Mound in both size and sheer spectacle, making it the largest animal effigy mound in the world. |

 | | The Serpent Mound acropolis is made up of shallow, stony and acidic soil, whereas the soil just to the west of the ridge is made up of loam and flood-deposited sediments, and one-half mile south of the mound the soil is made up of 10-20 inches of wind-deposited loess. |
