Serpent Mound, the world's largest effigy, is one of the world's greatest mysteries. It is a quarter-mile long serpent carved into the earth, and the world's largest prehistoric animal effigy (image). It is located on the bank of a monster meteorite crater. It is also the site of the nations first national park.

It might be called America's Stonehenge or great pyramid. It is a world's first for many reasons:

1. It is the largest animal image or effigy earthwork in the world (1,330 ft.).
2. It is one of world's greatest mysteries, its makers and purpose are unknown; it does not contain burials.
3. It was made to be seen from above, rather than ground level. It is more awesome that the Nazca lines of Peru, because the land had to be cleared before it was made.
4. It is astronomically aligned. Its head is aligned with the summer solstice, its coils with the winter solstice and the autumnal and spring equinox sunrises, and with the summer solstice sunrise.
5. It is carved into the side of one of world's largest meteorite craters (~ 5 mi. diameter), which is one of only a few such places in the US. The meteoric impact occurred in the Permian Period about 248 to 286 million years ago.
6. It is possible that the object that slamed into the earth to make the crater was an asteroid.
7. It was the first State Park in the US.
8. It is mysterious, because no meteorite was ever found in the area.
9. It is one of the most famous of all historic sites, one of the strangest, and listed by many sources as one of the wonders of the ancient world. It is a candidate for the United Nation's World Heritage list.
10. It is at the convergence of three distinct soil types.
11. It is near the area where flight was first developed (the Wright brothers in Dayton) and the birth place of Neil Armstrong (first person on another world) and John Glenn. It is
12. Underground caves exist in the area.
13. Many mysterious anomalies exist in the region, e.g., it lies at the center of three major physiographic regions. It lies between the unglaciated Appalachian plateau and glaciated Till Plain areas. It commands a view of the Appalachian Mountain foothills to the east and the plains to the west.
14. It is located in a region of three soil types.
15. It is near the intersection of three geological fault lines.
16. It is in the area of unusual magnetic activity.
17. The area is one of gravity anomalies and high concentrations of uranium near the surface. It contains iridium at levels up to 10 times the that typical of the Earth's crust.
18. It also contains soot that may come from scorched limestone, deormed sand grains, and fractured quatz.
19. Shatter cones like those found in Nevada at nuclear weapon test sites exist throughout the structure.


Its head overlooks a the brim of a gigantic meteorite crater, it has a body composed of 7 coils, and a triple coiled tail. Its head contains a giant oval, variously thought to be an egg or the sun. It is unknown when it was built, or by who, but thought to be at least a thousand years old or maybe much older.

It is one of four places in and around Dayton associated with the Wright Brothers, who built the world's first airplane and pioneered human flight. The Serpent Mound is also on the Interior Department's list of more than 40 additional earthworks left by Native American cultures, who made gigantic structures in precise geometric shapes more than 1,000 years ago.

About the ancient structures in Ohio, the Interior Department noted: "These are among the largest earthworks in the world that are not fortifications or defensive structures, and they contain extensive deposits of finely crafted artifacts. Their scale is imposing by any standard: the Great Pyramid of Cheops would have fit inside the Wright Earthworks; four structures the size of the Colosseum of Rome would fit in the Octagon; and the circle of monoliths at Stonehenge would fit into one of the small auxiliary earthwork circles adjacent to the Octagon."

Although places such as the Nazca lines of Peru are better known, the earthworks in the Eastern United states were much more difficult to build because the tress and vegetation had to be removed and the earth flattened.

The geological structure of the crater has been described as a central hub surrounded by two concentric rings. The outer ring is displaced downwards. A variety of outcroppings are found in the crater. The outer ring, the highest part of the structure risees to an elevation of 1120 feet. It has been described as a large upturned and broken mass. And a huge region that had sunk down several hundred feet, producing dislocations, faults, and upturning layers of rocks. However it is so deeply eroded and buried that little evidence exists on the surface.
