Description:

1070 CE
Earthwork/effigy mound

The head of the serpent aligns with the summer solstice sunset, and tail points to the winter solstice sunrise. It has been suggested that the curves in the body of the snake parallel lunar phases, or alternatively align with the two solstices and two equinoxes.
