A mysterious figure was captured roaming the woods in Colorado, sparking theories that the elusive Bigfoot has finally been found.

A whitewater rafting crew with the Colorado River Expedition was traveling down the Upper Colorado River on May 24 when they pulled ashore for a break.

Logan Kirk, the lead guide, told DailyMail.com that he and about 12 others had stopped for lunch when they spotted the creature roughly 500 yards away. 

'Someone yelled out that they saw a bear, so we started looking at it, and that's when we realized it was something else. It wasn't a bear. It was standing up there on the hillside,' he said. 'It was definitely bipedal, which really stood out to us. 

The video, which has been viewed millions of times online, shows a large, furry figure walking through dense pine trees. It stops in between two trees, appears to stare directly at the camera and then vanishes in the woods.

While many commenters are thrilled at the idea that Bigfoot may have been found, others believe it was either a person in a suit or a bear walking on two legs. 

Regardless, Kirk is planning a return expedition to the same spot as the sighting.

'We're gonna go up to see if we can find any evidence of what was going on up there, whether that's footprints or something else. Who knows? It's so hard in the rocks to actually get anything like that, but we want to see if there's anything there,' he said.

Others asked, 'Why is it always the same type of blurry, far-away footage of Bigfoot?'

While the sighting is likely a person in a suit or a bear, Colorado has had more than 100 reports of the human-like creature since March of this year.

'We're still trying to figure it out,' said Kirk. 'We've gone through the footage and zoomed in on the images, whatever it is, whether Bigfoot or some other creature.'

Stories of large, hairy, human-like beings go back centuries to ancient Indigenous cultures across North America. 

They spoke of 'Sasquatch,' a word meaning 'wild man.' 

The first widely publicized report of Bigfoot in modern times came in 1958, when journalist Andrew Genzoli of the Humboldt Times in California published a letter from a reader describing massive, mysterious footprints found near a logging site in Bluff Creek.

The letter sparked widespread interest, and follow-up articles, some playfully referring to the creature as 'Bigfoot,' helped launch the legend into the public imagination.

The most famous and still-debated piece of Bigfoot 'evidence' came in 1967, when Bob Gimlin and Roger Patterson filmed a now-iconic clip of a large, furry figure striding through the woods at Bluff Creek.

Known as the Patterson-Gimlin film, the footage was shot during the duo's expedition to find the elusive beast.

Both men were on horseback when they rounded a bend and spotted a towering, ape-like creature walking along the riverbed.

Its head and torso were sloped forward, back hunched, massive thighs flexing with each step, and long arms swinging at its sides.

Patterson's horse reared up in panic. He jumped off, grabbed his camera, and scrambled across the ground, waving the device in one hand and desperately trying to keep the creature in frame.

The shot steadied just long enough to capture the moment the creature turned to look over its right shoulder before it disappeared into the trees.

Years later, Bob Heironimus, a retired Pepsi bottler from Yakima, claimed he was the one in the costume used to stage the video.

But Gimlin, who is still alive, has always denied the story, insisting that what he and Patterson saw that day was a man in a suit, but Bigfoot.
