To anyone looking to visit this site, I hope you will take a minute to read through this first (or at least the wikipedia page).
As soon as I walked through the door, and saw the slapdash arrangement of their exhibit, I had a feeling something was not right here. I hadn't really read up on the site, and assumed we were dealing with a Native American settlement based on astronomical calculations. Little did I know the truth... which is, well, more entertaining, but a whole lot less sane.
The first box I examined by the door contained some stones with vague scratches (probably plow marks) that the signs proclaimed to be "Celtic Ogham (script)". The signs were very unprofessional and mostly incomprehensible, unhelpful, and/or irrelevant. So I walked up to the main desk and asked the teenage girl why a "4,000 year old site" would feature Celtic stones, when Northern Europeans didn't arrive in America until about 1,000 years ago (and even their "Vinland" was definitely not Salem, NH). She shrugged and said she had no idea, I would need to ask her boss.
Well alright, I paid my entrance fee, and walked into the video room. I'm glad nobody else was there, because the next five minutes consisted of a non-stop stream of WTFs emitting from my mouth. I may not be an archeologist, but I'm an academic, and I know pseudoscience and evasive rhetoric when I see it. Not one person in that video is a reputable scientist. And not only was there almost no mention of Native Americans, the entire video was a bunch of claptrap from a complete nut job who thinks this site was created by Celtic priests who somehow came to America 4,000 years ago. This, despite the complete absence of any indication or evidence of early Europeans whatsoever, of ANY kinds, ANYWHERE on the North American continent. Oh dear...
So while walking up to the site, I did a little research. Apparently every Professor of Archaeology in America who's been asked about this site agrees that it is a hoax, created in the 1920s, possibly built on some colonial root cellars from the 1800s or so. There is not a single reputable academic in the entire world who believes a word of the "America's Stonehenge"' claim. And the utter lack of any professionalism at the site strongly suggests the place is run by some amateur wackos with ridiculous conspiracies. They admit the guy in the 1920s moved the stones, but claim he only "restored them to where they belong". Uhuh. Which he magically knew, and conveniently did right when tourism was growing into the great American pastime.
And all the claims they make about having "carbon dated the stones"? Yeah... so stones don't contain carbon. You can't carbon date them. Simply physically impossible. Is any part true? Well, a few objects were carbon dated from a few hundred to four thousand years old, but they are all entirely consistent with early Native American settlements (hearths and such). And indeed, there IS such a settlement. Unfortunately, these wackos built their parking lot on top of it.
Is America's Stonehenge worth visiting? That's debatable. On the one hand, it makes for good entertainment, and they have ALPACAS! And who doesn't love alpacas? They're incredibly cute, even though they apparently hate people.
My main concern though, is that spreading this sort of pseudo-scientific claptrap (for the sake of profit) does more harm than good to the more gullible, uneducated and conspiracy minded members of society. Even worse, the site's insistence on an utterly impossible and implausible explanation of "Europeans magically getting to America 4K years ago and building this brilliant structure" REEKS of white supremacist ideology.
As you watch the video, explore the site, and see their utter refusal to seriously consider that Native Americans built this (fake) structure, it becomes blatantly obvious that the man who invented this was unwilling to credit Native Americans with the intelligence to construct this site, and therefore concocted an elaborate and utterly absurd myth about the 'superior white race' arriving here, because 'surely only their brilliance could have built this'. This, despite there being zero proof of Europeans here, and ample evidence of Native American settlements.
In short, the site intentionally disseminates false information for the purpose of propagating an absurd myth of white people's brilliance and resourcefulness. So while the Alpacas, evil as they may be, are unbearably cute and cuddly looking, I strongly suggest visiting this site for entertainment purposes only, and with some scientific information in your back pocket about the truth behind this hoax.
Oh, and don't get too close to the alpacas. They spit. read more
