An official with the Alaska Bureau of Land Management filmed a perplexing anomaly in the state's Chena River that has left viewers scratching their heads.
Craig McCaa was documenting the changing of the seasons at the popular rafting and fishing destination when he spotted a puzzling 12 to 15-foot-long oddity seemingly swimming in the river.
Unable to determine what the "strange thing" was, McCaa posted the video to the Alaska BLM Facebook page, leading to thousands of people watching the footage and offering their opinions.
McCaa theorized that the anomaly could be a piece of ice-covered rope, although he noted that other observers have proposed possibilities ranging from the prosaic, such as a giant sturgeon, to the fantastic, including the always-tantalizing 'sea monster.'
How one interprets the video likely depends on whether they think the anomalous object is moving on its own or simply being swayed by the force of the river.
A perplexing piece of footage purportedly captured by tourists visiting Alaska has left viewers baffled and wondering if it could be a sea creature of some kind.
The video begins with the tourists marveling at a glacier collapsing in front of them and then they seem to notice a series of unexplained dark objects protruding from the water nearby.
An additional three 'humps' pop up a few feet away from the first group of objects, suggesting that the entire collection is part of one larger body.
However, what may lie beneath the surface is open to speculation with some imagining fantastic possibility like a dragon and others theorizing that it is probably a native creature being mistaken for something 'out of this world.'
And, as can be expected, more cynical observers argue that the video is outright fake.
Unfortunately, aside from the alleged backstory, little else is known about the footage, including when it was taken or where in Alaska the incident happened.
Coming so soon after a more robust 'creature' sighting in Alaska made headlines around the world, the chances that this could be a clever hoax designed to capitalize on that story cannot be discounted.
