The Serpent Mound Tunnels:
If you ever go to serpents mound, a short walk along the trails leading away from the mounds will take you directly under the rock face of the mounds. Walking along the path below the mounds and deep into the sides of the bedrock, are numerous small “tunnels” into the rock. Some of the holes go into the bedrock very deep. Itï¿½s unknown how these holes were made, although it is loosely suggested that they originated from a prehistoric underground gas explosion. It is entertaining to think that they might have been associated in some way with snakes. The journey along the Serpent mound begins at the tail. When you approach the mounds, the first thing that you witness is a perfect spiral. This spiral feature is a well noted phenomenon around the ancient world. There are several good examples in the America’s, most notably those at Nazca and Chaco Canyon. Although the original significance of the spiral and labyrinthine form are lost to us now, they are commonly suggested to be related to the ‘inner journey’.
Service and Bradbery (9), write that the spiral refers to:
‘…the belly and navel (Neumann 1955). It is also seen as representing a Navel of the earth – the Omphalos…E.A.S Butterworth in ‘The Tree at the Navel of the Earth’ calls it the Omphalos sign…now seen as very ancient and very widespread (Roscher 1913), This fits well into the idea of megalith as places of interchange between the cosmic forces of the sky and earth’. 10
Walking from the Spiral along the serpent body is a peaceful and contemplative experience. The farther you walk along the Serpent, the more astronomical observatories you encounter. The undulations of the serpents body were designed to be orientated such that they align with the most significant moments of the Lunar and Solar calendars on both sides: While today many of these alignments are obscured by trees, in its original form and with the lines of sight cleared, the monument would have once been able to operate as a calendar for both cycles (Metonic).
The Snakes head: Some say the serpent has an ‘egg’ in its mouth, while others say it is ‘Eating the Sun’. The head is aligned to the summer solstice sunset, and acts as a wonderful observatory to view the solar precession. Facing away from the Cosmic egg and Serpent head, there is a platform that provides the most breathtaking view of the Impact area below. It seems likely that both the location of the mound and its design (the ‘egg’ it carries in its mouth), are both connected in some intricate way to the crater over which it lies coiled.
