Mariemont serpent mound could be world's largest
This serpent mound is 2,952 feet long, more than twice the length of the celebrated Great Serpent Mound in Adams County, which many believe to be the largest serpent effigy in the world.
“This Mariemont serpent mound is much better preserved than the one in Adams County, which was largely reconstructed,” Tankersley said. “The fact that this much of the Mariemont earthwork survives is miraculous.”
Part of the mound along Miami Bluff Drive is about 7 feet high, close to the original height of the entire earthwork when it was built, he said. Most of the remnants are about 3 feet high.
