Ross Hamilton has made some truly incredible discoveries about the
Great Serpent Mount in
Ohio. This ancient
Native America earthwork has got a real mystery to reveal.
Listen as
Whitley finds out the answer. How does the constellation
Draco figure into the story, and who, truly, does the serpent represent?
Linda Howe explores a much more modern mystery: what are those strange, hard-packed soils scientists see in the recent
Mars Photos.
The Great Serpent Mound is a 1,348-foot (
411 m)-long, three-foot-high prehistoric effigy mound located on a plateau of the
Serpent Mound crater along
Ohio Brush Creek in
Adams County, Ohio. Maintained within a park by the
Ohio Historical Society, it has been designated a
National Historic Landmark by the
United States Department of Interior.
The Serpent Mound of Ohio was first reported from surveys by Ephraim
Squire and
Edwin Davis in their historic volume
Ancient Monuments of the
Mississippi Valley, published in
1848 by the newly founded
Smithsonian Museum.
Researchers have attributed construction of the mound to three different prehistoric indigenous cultures. Although it was once thought to be
Adena in origin, now based on the use of more advanced technology, including carbon dating and evidence from
1996 studies, many scholars now believe that members of the
Fort Ancient culture built it about 1070 CE (plus or minus 70 years). There are still anomalies to be studied.
Serpent Mound is the largest serpent effigy in the world.
The dating of the design, the original construction, and the identity of the builders of the serpent effigy are three questions still debated in the disciplines of social science, including ethnology, archaeology, and anthropology. In addition, contemporary
American Indians have an interest in the site. Several attributions have been entered by academic, philosophic, and
Native American concerns regarding all three of these unknown factors of when designed, when built, and by whom.
Over the years, scholars have proposed that the mound was built by members of the
Adena culture, the
Hopewell culture, or the Fort Ancient culture
. In the 18th century the missionary
John Heckewelder reported that
Native Americans of the
Lenni Lenape (later
Delaware) nation told him the
Allegheny people had built the mound, as they lived in the
Ohio Valley in an ancient time. Both
Lenape and
Iroquois legends tell of the Allegheny or Allegewi
People, sometimes called Tallegewi. They were said to have lived in the Ohio Valley in a remotely ancient period, believed pre-Adena, i.e., Archaic or pre-Woodland period (before 1200
BCE). Because archaeological evidence suggests that ancient cultures were distinct and separate from more recent historic Native American cultures, academic accounts do not propose the Allegheny
Nation built the Serpent Mound.
Recently the dating of the site has been brought into question. While it has long been thought to be an Adena site based on slim evidence, a couple of radiocarbon dates from a small excavation raise the possibility that the mound is no more than a thousand years old.
Middle Ohio Valley people of the time were not known for building large earthworks, however; they did display a high regard for snakes as shown by the numerous copper serpentine pieces associated with them.
Radiocarbon dating of charcoal discovered within the mound in the
1990s indicated that people worked on the mound circa 1070 CE.
The Serpent Mound may have been designed in accord with the pattern of stars composing the constellation Draco. The star pattern of the constellation Draco fits with fair precision to the Serpent Mound, with the ancient
Pole Star, Thuban (α Draconis), at its geographical center within the first of seven coils from the head. The fact that the body of Serpent Mound follows the pattern of Draco may support various theses.
Putnam's 1865 refurbishment of the earthwork could have been correctly accomplished in that a comparison of
Romain's or
Fletcher and
Cameron's maps from the
1980s show how the margins of the
Serpent align with great accuracy to a large portion of Draco. Some researchers date the earthwork to around
5,000 years ago, based on the position of Draco, through the backward motion of precessionary circle of the ecliptic when Thuban was the Pole Star.
Alignment of the effigy to the Pole Star at that position also shows how true north may have been found. This was not known until
1987 because lodestone and modern compasses give incorrect readings at the site
