May 13, Friday the 13th and a full moon! We drove down to Serpent Mound to see it once again. Scientist think that the mound was built by one of three cultures, the Adena, Hopewell, or Fort Ancient Culture. It winds over the terrain for eight hundred feet and seven coils. The coils align with the summer and winter solstice and two lunar events. The mound also corresponds with the star patterns in the constellation Draco.
There is a tower so one can get a bird's eye view of the snake. The tower was built almost one hundred years ago and they keep it in good shape.
