I’m not surprised there is an American Stonehenge. There are Paleolithic astronomic structures all over Europe and down into the Middle East. Some, such as Newgrange, are as impressive as Stonehenge. Many are less massive, but are as intricate as Newgrange and Stonehenge in their tracking of astronomical movement. One in Egypt is shown over and over in that show that goes on and on about every human accomplishment coming from “an otherworldly source, as many theorists believe.”
Plotting the equinoxes and the solstices was a worldwide Paleolithic phenomena. Some writers propose the theory that a central Stone Age society spread the Stonehenge style astronomical calendar throughout the British Isles, Western Europe and into the Mediterranean area. Two books, which I find fascinating, expound on that theory. I recommend these books: Uriel’s Machine and Civilization One.
Uriel’s Machine references to passages in The Book of Enoch, an old Hebrew text that was favored by the occupants of Kumran. Part of it is said to tell how to build a Stonehenge type structure. Enoch also refers to the “watchers” who seem to manage the construction of the one of these structures. Might the watchers be those “otherworldly beings, as some theorist believe” or are they from a more advanced Paleolithic culture, as the authors of Uriel’s Machine suggest?
By reverse-engineering Stonehenge, the authors were able to deduce the construction methods used by the Stone Age people. They even show how prehistoric measurement systems were the basis for the pound, pint, and second. Yes the second is just one cycle of a pendulum made by tying a stone to a cord of a specific length.
Does American Stonehenge point straight to Stonehenge in England? Yes and no. See my sketch below. If you were to sight through two narrow slots that were a substantial distance apart, like looking through gun sights then you might be able to declare that your line of sight points to a distant place like England. But here there is no exact rear sight, and the front sight is a broad stone. By picking any point on the top of the front stone and by moving himself a foot right or left, an observer could claim a line of sight to almost any place in Northern Europe that he chooses.
The entire length of England has an included angle of only 5 degrees when measured from a point in New England, therefore almost any variance at the front or rear sight point could miss the country completely.
