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. .
