Roger Dickey is an avid geography fan and intrepid traveler. He is a member of Atlas Obscura who tracks down earth's anomalies and visits them. He came by his interests honestly, from his mother, Ellie Talburtt. Together they went to explore Michigan’s Isle Royale, which has the title of the US's least-visited national park.
What had brought them there, and into this rather dicey situation, was something called Moose Boulder, a kind of geological matryoshka. Here’s what makes Moose Boulder special, from the outside in: Lake Superior is the world’s largest freshwater lake, and its largest island is Isle Royale, whose largest lake is called Siskiwit, whose largest island is called Ryan. According to Wikipedia, at least, Ryan Island is home to a seasonal pond called Moose Flats that, when flooded, contains its own island—Moose Boulder. This makes it “the largest island in the largest lake on the largest island in the largest lake on the largest island in the largest lake in the world.” Pity it’s not in Greenland, it could have gone all the way.
Dickey did his research before going to Ryan Island. He looked up every mention of Moose Boulder on the internet, and while he found plenty of mentions, he never found anyone who had actually been there. Every path he explored turned out to be dead links, people who couldn't be found, and circular citations. He became convinced that Moose Boulder was a nonexistent hoax, but that didn't stop him from looking. Dickey and Talburtt's trip to Isle Royale held more adventure than they were expecting. Read about the trip and the research into Moose Boulder at (where else?) Atlas Obscura.
