They Built Structures Big Enough to Hold the Roman Colosseum
The numbers tell you how ambitious they were. The octagon at Newark, Ohio stretches 1,720 feet across and covers 50 acres.

That’s room for 100 football fields. The earthen walls rise 12 feet high and form perfect geometric shapes: circles, squares, octagons.

"Not just at one village or one ceremonial center, but across their entire territory. A square earthwork in Chillicothe matches a square in Newark 60 miles away, down to the foot"

👉🏻"The precision shows they had surveyors, engineers, and a way to share exact measurements across vast distances".

The Marietta Works

NOTE: Marietta was the first organized settlement in the Northwest Territory under the Northwest Ordinance (1788) It is located at the confluence of the Ohio and Muskingum Rivers. The city of Marietta was incorporated in 1800. The process for Ohio to become a state began in 1802 with the Enabling Act. As the fairy tale goes, Ohio became a state in 1803 but was retroactively enacted by Dwight D. Eisenhower in 1953 - exactly 150 years after the fact. Timelines....... Plans.......

👆🏻Any connection here?👇🏻

I have read and researched so much about the mounds of Ohio and other states. I think the story of our real history lies in the mounds. The absolute beauty in the design, the sacred geometry, the alignment with the solstices, the lunar cycles.... The locations..... This is not coincidence. This is ultimate design and mastery. The pure, original Masons were infiltrated. Their knowledge stolen and flipped upside down. I truly wonder if what we are looking at when we look at the mounds is the work of the true, original, divine Masons. The ancient builders who understood and revered the Grand Architect of the Universe. In my mind, it fits.

.....history and timelines recorded UPON the earth.

Ancient monuments, megaliths and earthworks perhaps??

Large rock found in the creek bed just over the hill from the "front" of the Great Serpent Mound. Do you see it?

I truly have to wonder....... The Kundalini is referred to as the "serpent".
