The Ohio Snake Mound Ancient Earthwork, located in Adams County, Ohio, is one of the most fascinating and mysterious prehistoric monuments in the United States. This massive earthen structure, built by the Hopewell culture between 300 and 100 BCE, stretches over 1,300 feet in length and is an average of 4.5 feet in height. The mound is designed in the shape of a serpent, with seven distinct coils, and is considered one of the most impressive examples of prehistoric earthen architecture in the world.
The construction of the Ohio Snake Mound is a testament to the advanced engineering and mathematical skills of the Hopewell people. The mound is aligned with the summer solstice sunrise, and its coils are designed to mirror the pattern of the constellation Draco, which was an important celestial body in Hopewell cosmology. The mound's shape and orientation are also believed to have been influenced by the local topography, with the coils following the natural contours of the land. According to Dr. Bradley Lepper, an archaeologist with the Ohio History Connection, "The Ohio Snake Mound is a remarkable example of the Hopewell culture's ability to combine astronomical observations with geological features to create a complex and meaningful ceremonial landscape."

The History and Significance of the Ohio Snake Mound

The Ohio Snake Mound was built during the Middle Woodland period, a time of significant cultural and economic change in the region. The Hopewell culture, which flourished from around 200 BCE to 500 CE, is known for its elaborate earthen structures, which were often built for ceremonial and ritual purposes. The Ohio Snake Mound is one of the most impressive examples of these structures, and its design and construction reflect the advanced knowledge and skills of the Hopewell people. As noted by Dr. Lynne Sullivan, an archaeologist with the University of Tennessee, “The Ohio Snake Mound is a remarkable example of the Hopewell culture’s ability to create complex and meaningful ceremonial landscapes that reflect their deep understanding of the natural world.”
The Design and Construction of the Mound
The Ohio Snake Mound is a masterpiece of prehistoric engineering, with a design that is both aesthetically pleasing and mathematically precise. The mound is built from a combination of earth and stone, with a core of clay and a outer layer of soil and gravel. The coils of the serpent are designed to be proportional to each other, with each coil decreasing in size as it approaches the tail of the serpent. The mound’s shape and orientation are also believed to have been influenced by the local topography, with the coils following the natural contours of the land. A study published in the Journal of Archaeological Science found that the mound’s design is consistent with the principles of sacred geometry, which were used by many ancient cultures to create symbolic and meaningful structures.
