Lagarfljotsormurinn, worm or simply Iceland Worm Monster( or Iceland's Loch Ness Monster ) is an Icelandic lake cryptid. The worm is purportedly located in Lagarfljt Lake, a freshwater, below-sea-level, glacial-fed body of water in Egilsstair. The water visibility is incredibly poor as a result of siltation, and the creature--if it does exist--has not been scientifically studied.
