Indiana's Adena Serpent Mound

Indiana's Adena Serpent Mound

Indiana's Serpent Mound undulates in ninety-degree turns with a large oval-shaped head.  It is identical to another Serpent Mound that was diagrammed above in Warren County, Ohio.

Thick freeezing fog prohibited a better picture of the Serpent Mound that is still visible in this grassy field.
