A YouTuber used a GoPro to capture what the bottom of the "world's most dangerous river" looks like and the results have left many viewers terrified.
Jack Harding, who goes by the handle @jackasnacks, visited The Strid, which is a famous river located in Yorkshire, UK.
The hiking area is just two meters wide at its narrowest point, but it hides a horrifying secret beneath its picturesque surface.
Stretching 65 miles through the Wharfe Valley and flowing into the River Ouse, the river reaches depths of over 200 feet. Falling into its dangerous waters is almost always fatal.
With no recorded survivors of accidents in The Strid, the river’s reputation is bone-chilling. Many of those who’ve met their fate reportedly tried to leap across the narrow channel, unaware of what's lurking below.
According to the Yorkshire Dales website, the Strid “mercilessly sucks its victims into the underwater caves and eroded tunnels which lie hidden underneath each side of the rocky channel".
Harding decided to risk his life to explore the Strid’s mysteries by throwing a GoPro into the river so he could capture a glimpse of what lies beneath.
It wasn’t a smooth operation as at one point, the device got stuck between rocks for nearly 30 minutes. But eventually, he retrieved the camera and unveiled footage from depths reaching between 25 and 30 meters.
Watch the video below:The footage revealed powerful currents and something particularly unnerving - air bubbles trapped at extreme depths. Many viewers took to the comment section to share their reactions.
"The most frightening thing there is the bubbles at 25-30m. It shows just how powerful the downwards current is at that point," one person commented. "If it can take air that far down (and further) then it's easy to see why a person falling in or being swept into that section is not coming up again!"
Another viewer, identifying as a diver, was horrified: "Dude, as a diver, I cannot imagine anything more terrifying than seeing air bubbles [constrained] in current at that depth, that came from the surface vs. a diver's exhaust gas."
"It takes a huge amount of energy to drag air down there. And if that's cavitation... well, just look up how pressure that requires! I'm honestly amazed you got your camera back!" they added.
"The fact the bubbles haven’t been about to rise all the way down at 30 meters is terrifying, that downward current is so strong," a third shared.
Harding's video has only cemented The Strid’s deadly reputation. “This was fascinating and made it immediately clear why this river is so deadly,” a fourth concluded.
