Here’s a nicely creepy borderlands of science/urban legend/conspiracy theory video about a hole that has no bottom.
80,000 feet worth of fishing line found no bottom. Plus animals avoided it, and radios went crazy, when they weren’t picking up signals from 30 years before.
Then the government took it over.
Much more paranormal weirdness ensues
Was it real? Well, as real as anything else with a Wikipedia entry featured on Art Bell.
Good luck finding it on map…
