Mysterious sounds heard from frozen lake sparks bizarre alien theory

“Mysterious” sounds heard underneath a frozen lake in the US have prompted a wild theory about what it could be.

Strange “UFO sounds” coming from under a frozen lake in the US have sparked a bizarre alien base conspiracy.

But science may have some more mundane explanations as to the source of the mystery sounds.

Recordings taken from Steamboat Springs in Colorado were made by an employee of the Colorado Parks and Wildlife Service on December 4, The Sun reports.

The staff member posted them to Twitter, which has subsequently been shared to UFO Sightings Daily, where they have been described as “strange Star Wars sounds”.

Analysing the audio, conspiracy theorist Scott C. Waring said: “White sphere UFOs have been recorded and eyewitnesses by thousand of residents of Colorado over the last few years.

“The signals point to there being an alien base deep below the lake, which amplifies the sounds below due to it being frozen … it acts as an amplifier.

Alien sounds were recorded from a frozen lake.

“Alien bases are never small. Most are 3-6km deep and cover an area of about 5km and even have their own weather system … with chances of rain.

“This is 100 per cent proof of an alien base below this lake in Colorado.

“But … if signals can travel up from the alien base, then it would also work to send signals back down to the base.

“A loud enough speaker placed in a dugout 1m deep ice hole at the centre of the lake would be sufficient to send them a sonic signal.

“But … what would you say? In the wrong hands, it could cause an alien military response.”

However, there seems to be a more plausible explanation for the noise.

According to National Public Radio, shifting in the ice of a frozen lake causes high and low sound frequencies.

The vibrations move through the ice, but the high frequencies move faster than the low frequencies.

But the Steamboat Springs noises may just a simple part of nature.

And YouTube viewers were in agreement.

“Ice makes this noise at random times when it gets thicker and thinner,” said one.

Another agreed: “I’ve heard this sounds myself in winters when it’s ice. It’s got nothing to do with aliens.”

Another joked: “That’s the sound the McDonald’s ice cream machine makes to let you know it’s out of order.”
