For example, this one didn't end until someone physically went to Isle Royale and looked for it:
https://www.atlasobscura.com/articles/m ... r-debunkedHe had found another article about Moose Boulder, published in 2009, that cited Wikipedia as its source of information. But the information about Moose Boulder had been added to Siskiwit Lake’s Wikipedia page in 2012. It was like a scene in a bad horror movie in which someone gets a phone call from a dead person. Dickey joked with his girlfriend that perhaps Moose Boulder does exist, but only in some kind of “temporal anomaly.”
Here’s the rub: Wikipedia is a nesting doll, too. Before a page for Siskiwit Lake had been added to the site, the page for Isle Royale had pointed readers to Moose Boulder, and had been doing so since 2009. It was put there by a different user than the one who added it to the Siskiwit page in 2012. Either way, that’s where the trail goes cold, and there’s no other evidence that the place exists. The identity of that first Wikipedia user to write about it—with those completely unrelated sources—remains a mystery, but all available evidence suggests that it was a person having a laugh, nothing more.
