Remember the Lagarfljótsormurinn – the Icelandic “wurm” or serpent that was a viral story from 2012? Another example of the same phenomenon has appeared in an Alaskan river.
Here is the Iceland worm to jog your memory. Note that the object does not move through the river – it stays in the same place.
The apparent “serpent” undulating (horizontally) in an icy river turned out to clearly be iced-up fish netting, cloth, or vegetation that was moved by the current.
The exact same features can be seen in this latest “mystery” video taken in the Chena River by the Bureau of Land Management Fairbanks District Office staff.
No mystery here. You can see pieces are iced over. No reptile can live in these icy conditions. It’s not supernatural. It’s a string of fabric or netting coated with ice moving in the current. Of course, by zooming in on the object, you can’t tell it’s not moving relative to shore. Only when the frame of reference is large enough that you can see it’s stationary. Watch for this video to be used, cropped, to promote the existence of a river monster. That’s deceptive.
