So what’s the story?

Many years ago in a place thats now called Ohio, the original inhabitants of the land decided to create an effigy to the serpent. The large-scale 1348-foot-long mound not is not only the built in the shape of a serpent, but is also built with celestial alignments. The tongue points to the sunset on the summer solstice, the first bump points to the summer solstice sunrise, the second bump to the equinox sunrise, and the third bump to the winter solstice sunrise.

Geometry:

The head of the Serpent Mound is composed of ellipses elongated by circular arcs. The body of the serpent can be broken down into circles with tangent lines running between them, with the end of the tail as a spiral.

The entirety of the geometry is offset to its final form through the act of mounding.
