added by archaeologs Large ritual earth mound near Locust Grove, Ohio, with the form of a curved serpent holding either an egg or a frog. The mound is associated with a nearby burial mound of the Adena culture. At 405 meters long, 1-2 meters high, it is probably the largest serpent effigy in the world.
added by archaeologs A ritual mound located in Adams County, Ohio, USA, and constructed in the sinuous form of a stylized serpent, holding an egg, or possibly a frog, in its jaws. At 386 metres long, 1.2-1.5 metres high, and with an average body-width of 6 metres, it is probably the largest serpent effigy in the world. Although no cultural material has been found within the mound, its proximity to an Adena village and burial mound testify to its most likely cultural affiliation.
