Is There Any Real Bigfoot Evidence?

Is There Enough Evidence For Me to Believe in Bigfoot?

There have been reported sightings of Bigfoot, or Sasquatch, the alleged large, elusive primate, throughout wooded areas across North America. The Sasquatch is a part of ancient Native North American folklore, especially in the Pacific Northwest.

Years ago I had come to the conclusion that these sightings were all tall tales, hoaxes, or mis-identifications of other large mammals, or even of human "mountain men" wrapped in furs to stay warm.

Really, how could there be another large primate besides humans living in North America when there has been no "real" evidence, such as in clear videos or photos, or a real body found somewhere?

Recently, though, I've decided that there might be something to all these sightings. Sure, many of the Sasquatch sightings are probably incidences of "mistaken identity" or downright hoaxes, but other sightings are more difficult to explain away.

While there's no Bigfoot body to examine yet (at least none that has been publicly shown) to scientifically prove that it exists, there's still plenty of physical evidence that's worth looking into.

Why Do I Entertain the Possibility That Bigfoot Exists?

I want to believe, but I still need more convincing

First of all, I'm still mostly a skeptic. I know that many people are very suggestible, and may jump to conclusions about what they see or hear or read.

But not too long ago, there was a news article in our local paper that reported Bigfoot sightings in Michigan, including our county. Holy cow!

I started laughing because of the sheer implausibility of it all! Up until that article I assumed Sasquatch sightings were all in the Pacific Northwest area -- in heavily forested rugged mountainous areas far away from any major human habitation. But after some research, I discovered that there have been Bigfoot sightings (or Sasquatch, or Skunk Ape, or Wild Man of the Woods, or the Boggy Creek Monster, among many other names) in large wooded areas across the US and Canada.

You'll note from the map that most sightings take place in the Pacific Northwest, but there are also many sightings in Texas, Florida, and Ohio. My state, Michigan (north of Ohio) also has some sightings. Very cool! What are these people seeing?

Evidence For Sasquatch / Bigfoot

"Physical evidence" vs "Physical Remains"

Very likely most skeptics won't believe that Bigfoot exists until there's a dead body or physical remains to examine. Until then they'll say that there's no scientific evidence that Bigfoot is real.

I understand how these skeptics feel. But even though there is no body to examine, there's other physical evidence to look at. Much of it is inconclusive, but some of it is pretty darn convincing to me!

Possible physical evidence that has been collected and examined includes:

  • Hair samples - including DNA samples
  • Scat (yup, Bigfoot poops too)
  • Footprint casts

And related:

  • Audio evidence

Other clues that might point to Bigfoot / Sasquatch in a particular area (besides visually spotting one) include:

  • Foul odor, kind of like a skunk
  • Knockings on trees and vocalizations
  • Broken branches arranged in shelter-like arrangements

And those who say they had a very good look at a Sasquatch say:

  • It's BIG
  • It's HAIRY (often auburn hair color)
  • It's FAST
  • It walks with a compliant gait (bent knee gait)

Image above from screenshot of 1967 view of Bigfoot by Patterson and Gimlin, on Wikipedia, and cited as fair use.

Physical Evidence of Bigfoot

Let's take a short look at the three forms of physical evidence that I mentioned above.

Hair samples

People have come across and collected hair samples that they think may be from a Bigfoot / Sasquatch. Unfortunately hair analysis is an inexact science, and a KNOWN sample is needed to compare other hair samples to it. There's no KNOWN Bigfoot hair sample yet. But there have been some interesting results from what little hair analysts could determine from some of the samples.

In the 1960s a few strands of "Sasquatch hair" were examined that had human and animal characteristics, but didn't match any other known animal.

But in another Sasquatch hair analysis, from the Yukon in 2005, the hairs were determined unequivocally to be....bison hair. How disappointing!

Soon there'll be more testing, at Oxford University of England. In May 2012, Oxford put out a request for Sasquatch and Yeti hair samples for DNA testing . A negative result wouldn't automatically mean that this elusive primate doesn't exist, although it would certainly be disappointing. But a positive result would be mind-boggling!

Update - July 2014

Earlier I wrote that Oxford geneticist Bryan Sykes had samples of purported Bigfoot and Yeti hair and tissue submitted to his lab to be analyzed. The results are back, and alas, most of the samples are from known animals including black bears, cows, a porcupine, a get the picture.

But a very cool finding was that two hair samples attributed to the Yeti, or Abominable Snowman, were a genetic match to the jawbone of an extinct polar bear from over 40,000 years ago. So this type of polar bear may still exist, and it very well may be the animal that people call a Yeti. So the Yeti is not an ape-like creature, but a type of bear. That makes sense to me!

Ahh, but now an additional update as of December 2014

Even world-renowned scientists make errors, or their lab workers do. Apparently the DNA that was said to be a match to the jawbone of an extinct polar bear is really a match to modern day polar bears.

Sasquatch Scat

Yup, Sasquatches poop too. And some people think they've found a few Sasquatch scat samples ("scat" refers to the fecal matter of animals). But since no one has actually seen a Bigfoot leave his pile, just as with the problem of identifying Sasquatch hair, there's no positively identified sample to compare it to.

But purported Sasquatch / Bigfoot scat is LARGE. Supposedly it's sometimes difficult to tell apart from bear or human feces, although it's usually larger than either.

The feces or scat of different species generally contain species-specific parasites. So the parasites of bear scat wouldn't be the same as in human feces. There've been at least a couple of possible Sasquatch scat from North America that have been analyzed in labs, and in one sample, the parasites that were present are found in some species of primates, but not in humans. Another sample showed parasites that are found in Native American tribes, or from humans from certain areas of China. So....maybe that sample was from a human out in the woods.

Bigfoot Footprint Casts

Of the three types of physical evidence that we're looking at on this page, footprint casts seem to give the strongest evidence of the existence of Bigfoot or Sasquatch.

There have been hundreds of Bigfoot footprint casts taken over the years and hundreds of miles apart from each other. Watch the following video to hear what two experts, CSI Officer Jimmy Chilcutt, and Professor of Anthropology, Jeff Meldrum, have to say about their examinations of footprint castings of Bigfoot.

Crime scene investigator and fingerprint expert, Officer Jimmy Chilcutt, has studied the dermal ridges of footprint castings of purported Bigfoots and has compared them with other primates, including humans. He believes that these footprint casts are not hoaxes, but are made by a primate in North America that is not human. He points out that human dermal ridges run across the width of the foot (look at your own feet, or a friend's, and check this for yourself). On other primates, these ridges run more diagonally. On the possible Bigfoot castings, there are ridges that run vertically down the side of the foot. These are not human footprints! Chilcutt firmly believes that these footprints are of an unknown primate in North America.

Jeff Meldrum, Professor of Anthropology at Idaho State University, has examined hundreds of Bigfoot footprint castings, looking at the variation of toe position, including from casts of a series of prints from single trackways. The footprints, including toe position and the spread of toes, vary depending on the substrate where the footprints were taken from. If these were forged, there wouldn't be the variability along the length of the trackway. Meldrum says he'd be more surprised to find out that all of these footprints were shown to be fakes than he would be to learn that Bigfoot is real.

Audio Evidence

Sasquatch / Bigfoot vocalizations

There are many recordings of what people think are Sasquatch / Bigfoot howling, screaming, whooping, growing, or even "talking". I'm not at all convinced that most of these are Bigfoot -- there are many other mammals and birds that have weird and unusual sounds -- but some of these recordings are very strange indeed.

Here are a couple of sites with Bigfoot sound samples that you can listen to:

Scott Nelson says he has audio proof of Bigfoot - YouTube video

Scott Nelson, currently a professor at Wentworth College in Missouri, spent 17 years as a cryptolinguist in the U.S. Navy, intercepting and decoding Russian communications.

A few years ago he was helping his son who was writing a school report on Bigfoot, and they came across recordings of purported Bigfoot vocalizations from the early 1970s in the Sierra Nevada Mountains. Given his experience in the Navy, and listening to these sounds, Nelson concluded:

  • He was hearing language
  • The language was not human
  • This was not faked

Since then, Scott Nelson has become a Bigfoot believer and researcher.

Is This a Photo of a Baby Bigfoot?

Possible Bigfoot child in northern Ontario

The photo above was taken with an iPod by a young girl when she was vacationing with her family in Wunnumin Lake, Ontario (see map marker A) in August 2012. She had been following her family through a clearing and saw this small hairy creature in the clearing. The girl hid and took her iPod photo, then the creature walked off. She didn't tell her mother until a couple days later.

Wunnumin Lake has had a number of Bigfoot / Sasquatch sightings over the years, and people speculate that there's a family of Bigfoots living in the area.

Of course sightings and somewhat blurry photographs aren't irrefutable evidence for the existence of Bigfoot, but they point to the possibility of its existence. (The people who've seen them believe!)

Read Wunnumin Lake's mysterious Bigfoot family for reports on some of the recent encounters in that area. (The article is also one of the sources for the photo, above.)

      About 60 years ago I was with my parents and another couple riding on a back road here in Maine. The other man was a deputy sheriff at the time and as we passed a certain section of road. He related that a creature which was described as what we now call big foot had been sighted there. It was laughed of as the locals were known to be not so highly educated an prone to strong drink. This story has stuck with me over the years. I always wonder when I pass this area today.

      I also have a friend who was fishing in Northern Maine woods an was cleaning fish when a very strong unpleasant odor appeared. He had heard Bigfoot stories an vacated the area. Re joining friend they asked what he had been doing as the odor permeated his clothing.

      This was a fascinating account to read! You are lucky (I think) to have had this experience, although you are also lucky that he didn't seriously injure you with his rocks! Much as I say I would like to see a Sasquatch, I don't want to be in one's line of fire when it's throwing rocks....

      I have seen it, heard it scream and growl, throw rocks, smelled the foul odor, heard it speak, and I was injured by one. Here is my siting report.

      I'd love to see proof that they're real too! People who say they have seen Bigfoot have all sorts of reasons why proof is hard to come by, but I'd think someone by now could've found something incontrovertible.

      I have not ever seen a Bigfoot. Although, I am more than open to seeing one. I cannot prove them, but would love to. Disappointed with those that say they did, without proof. It would be cool, but without real evidence it is a myth.

      @Snakesmum: It is disappointing, but it's certainly better to know that these samples are "just" from bears or whatever, and not Sasquatch. It is cool, though, that a couple of samples of the DNA match that of a 40,000 year old jawbone from a polar bear. I hear that Sykes is organizing an expedition to see if they can find one of these bears (perhaps the "real" yeti, which is a bear, and not a primate...).

      This week the final of 3 episodes about yeti, bigfoot, etc., was shown on TV here, including the DNA studies done by Professor Bryan Sykes of Oxford University. It seems that none of the samples were proven to be anything unusual, and many were actually bear hairs, including some from Russia. It was disappointing for the enthusiasts who supplied the samples of hair, etc., but research is still going on into this fascinating subject.

      As far as major discoveries go, next to finding other intelligent life in the universe, I think finding bigfoot has to be the biggest. I'm kinda disinclined to believe though.

      Very interesting! I'm a skeptic but I also won't rule anything out. I spent a day with a man last summer who believes and studies sightings. He shared a lot of scientific data with me about the reality of "big foot". It gets you thinking... You do a nice job of presenting the evidence here.

      Interesting article! It is amazing that not only is there stories about Bigfoot from modern days, but these stories go back thousands of years. Even teddy Roosevelt and Lewis and Clark mention Bigfoot. Good lens!

      @grj1647: Thanks, I think it's a fascinating subject, but I've only been paying attention to it for about half a year (my curiosity was piqued by something a friend said -- she may have seen a Bigfoot). I hadn't realized that Lewis and Clark mention Bigfoot but it certainly makes sense that they did.

      Supposedly, there is a DNA Research Paper that is going to be published proving the existence of bigfoot by Dr. Melba Ketchum. It was supposed to have passed peer review. One of the samples was suppose to be an actual piece of flesh cut from a bigfoot that was shot and killed in California, now known as the Sierra kill. This and lots of other interesting stories at for you bigfoot fans.

      If you take a poll of urban dwellers maybe one in twenty believe in bigfoot, but if you ask those that live in rural areas one in three is about right. What's that tell you?

      @EEWorkouts: That's pretty cool! I've read that the Skunk Ape is another name for Bigfoot found in Florida. And they usually have reddish, or auburn, hair.

      I've listened to some vocalizations that are online, and some sound quite eerie! (And others sound like they might be wolves or owls instead....).

      I have not seen it myself, but there are numerous reports in the Florida Everglades of a hairy, reddish, ape like creature. There are even vocalizations that have been recorded. A relative of mine even has a friend that swears that he saw one on his property and keeps it from his wife because she would want to move.
