Cahokia Woodhenge: Solstice and lunar alignments match European Stonehenge. Cahokia Woodhenge had the same number of rings as European Stonehenge and the same plane of the rings A beaker with identical symbolism to European Beaker Culture was found at Cahokia Feature 309 The solstice angle aligns from the center of the wooden post rings at the site
Cahokia's Woodhenge featured multiple timber circles (I through V) of different diameters with varying post counts. The site functioned as a solar calendar tracking sun angles. Woodhenge was positioned roughly 850 meters west of Monks Mound for equinox alignment. Mound 72 has been studied for potential lunar alignments.
Key facts claimed:
- Cahokia Woodhenge had five timber circles (I through V), with posts arranged in partial arcs rather than complete rings
- A beaker with European Beaker Culture symbolism was found at Cahokia Feature 309
- The solstice angle aligns from the center of the wooden post rings at the site
- The site functioned as a solar calendar tracking the angle of the sun rising
- Woodhenge was positioned roughly 850 meters (approximately half a mile) west of Monks Mound, aligned with the equinox
Key Facts
- Cahokia Woodhenge had the same number of rings as European Stonehenge and the same plane of the rings
- A beaker with identical symbolism to European Beaker Culture was found at Cahokia Feature 309
- The solstice angle aligns from the center of the wooden post rings at the site
- The site functioned as a solar calendar tracking the angle of the sun rising
- Woodhenge was positioned directly west of Monks Mound, aligned with the equinox
- Solstice, maximum lunar declination, and minimum lunar declination angles were built into the site configuration
- Mound 72 is positioned at the lunar declination angle from the Woodhenge and served as a lunar mound
- The average angle of 92 Kokia points measured is 27.1 degrees, nearly identical to maximum lunar declination in mid-winter
- Professor Al Fang at Illinois State University independently confirmed the astronomical alignments encoded in the artifacts
