Hopewell Mound Builder's Use of the Length of 250 Feet to Symbolize the Sun and the Serpent.

    In the Middle Woodland Period when the Beaker People had merged with the Hopewell Sioux, there was a change in the size of the Sun Temples or Henges from 660 feet in circumference or 210 feet in diameter to 250 feet in diameter.

Two henges located in Chillicothe, Ohio that were aligned to the Equinox sunrise and sunset. They are both 250 feet in diameter.

A group of four henges also located in Chillicothe, Ohio that were also 250 feet in circumference. Three of the henges are aligned to the Equinox sunrise with another aligned to the south.

The Dunlap Works in Chillicothe, Ohio also had a circle that was 250 feet in circumference.

To the northwest of Mound City in Chillicothe, Ohio was another Sun Temple (henge) that was aligned to the Equinox sunrise and 250 feet in circumference.

At the New Castle, Indiana henge site was another Sun Temple with an alignment to the equinox sunrise and a diameter of 250 feet.

This serpentine work that was located at the bottom of Spruce Hill was also constructed of stone. The length of 250 feet has a symbolic parallel with the serpent. We could deduce that the Serpent and the sun were both represented by the length of 250 feet.
