Bigfoot, also known as Sasquatch, is a large, hairy, ape- or human-like cryptid said to inhabit forests across North America, particularly the Pacific Northwest.[1] It is among the best-known cryptids in the world, has become a genuine subculture with its own dedicated researchers, conferences and museums, and remains, alongside the Loch Ness Monster, one of cryptozoology's two most iconic and enduring cases.
Description
Bigfoot is typically described as a large, muscular, bipedal creature covered in dark hair, standing anywhere from roughly six to nine feet tall in most accounts, with some more extreme reports claiming considerably taller figures.[2] Commonly reported features include broad shoulders, an apparent absence of a visible neck, and long arms — a combination sceptics frequently attribute to misidentification of a bear standing upright.[3] The creature's namesake footprints are claimed to run as large as 24 inches long; some recovered casts have shown claw marks, a detail more consistent with known clawed animals such as bears than with any primate.[2][1]
Etymology and names
The name Sasquatch was coined in 1929 by Indian Agent and teacher J. W. Burns, based on sasq'ets, a Halq'emeylem word roughly meaning "hairy man," used to describe wild figures in stories he collected while working with the Sts'ailes Nation in British Columbia.[4]
The name Bigfoot has a separate, later origin. In 1958, bulldozer operator Jerry Crew discovered large, human-like footprints at a logging site in Humboldt County, California; the story was picked up by journalist Andrew Genzoli of the Humboldt Times, and the name "Bigfoot" entered wide circulation from there.[5] In 2002, the family of Crew's deceased coworker Ray Wallace revealed a set of large carved wooden feet, stating Wallace had secretly made the original tracks himself.[6] Wallace said he had learned the trick from Rant Mullens, a forester who separately admitted in 1982 to using carved wooden feet decades earlier to frighten berry-pickers in Washington state.[7]
Many North American regions have their own local names for similar reported creatures — including the skunk ape in Florida, the Fouke Monster in Arkansas, and the Mogollon Monster in Arizona — reflecting a genuinely widespread pattern of regional wild-man folklore rather than one single tradition.[8]
Folklore and early history
Tales of large, hair-covered wild humanoids substantially predate the modern "Bigfoot" label, appearing across numerous Indigenous North American traditions as well as in the European "wild man of the woods" folklore brought by settlers.[9] Anthropologist John A. McClelland has argued that a Pacific Northwest Indigenous tradition describing a giant hair-covered figure, Tsonoqua, is a likely origin point for the wider Sasquatch legend.[10] Other regional traditions include the Iroquois Genoskwa ("Stone Giant") and stories recorded among the Lummi of creatures called Ts'emekwes.[11]
One frequently cited early written account comes from Theodore Roosevelt's 1893 book The Wilderness Hunter, which relates a story told to him by an elderly trapper about a foul-smelling, bipedal creature that stalked his camp and reportedly killed his companion.[12] The 1924 "Ape Canyon" incident, in which prospectors near Mount St. Helens reported a violent confrontation with "ape-men," was investigated by the US Forest Service at the time and concluded to lack compelling supporting evidence.[13]
The Patterson–Gimlin film
On 20 October 1967, Roger Patterson and Robert Gimlin filmed roughly a minute of footage at Bluff Creek, California, which they said depicted an encounter with a Bigfoot; the resulting Patterson–Gimlin film became the single most iconic piece of Bigfoot evidence ever produced, and remains heavily scrutinised and debated to this day.[14] Academic reviewers have generally found the film provides no data of genuine scientific value, and a hoax involving a costumed performer remains the most commonly proposed explanation.[15]
Proposed explanations
Bear misidentification
Scientists most commonly attribute Bigfoot sightings to misidentified American black bears, particularly bears observed at a distance, in poor light, or standing upright — a posture bears can adopt, especially when injured.[16] A 2009 ecological niche modelling study in the Journal of Biogeography found that the geographic pattern of reported Bigfoot sightings closely matched the known range and habitat preferences of the American black bear, concluding this made bear misidentification a highly plausible explanation for the pattern as a whole.[17] Data scientist Floe Foxon reached a similar conclusion in 2023, finding sighting frequency closely tracked local black bear population density.[18]
The Gigantopithecus hypothesis
Some Bigfoot proponents, including physical anthropologist Grover Krantz, proposed the creature could be a surviving population of Gigantopithecus blacki, a large extinct ape known from fossil remains in Asia.[19] No Gigantopithecus fossils have ever been found in the Americas, and the scientific consensus holds the species was quadrupedal, based on its enormous estimated mass — directly undermining the case for it as an ancestor of an upright, bipedal Bigfoot.[20] Anthropologist Matt Cartmill has separately argued that the physical traits attributed to Bigfoot — upright bipedalism, buttocks, a permanently adducted big toe — are specifically hominin traits unlikely to have evolved independently in a non-hominin ape lineage such as Gigantopithecus.[21]
DNA evidence
The most rigorous genetic study of purported Bigfoot material to date was published in Proceedings of the Royal Society B in 2014, led by a team from the University of Oxford and Lausanne's Cantonal Museum of Zoology. Analysing 30 hair samples submitted from around the world as likely Bigfoot, Yeti or other "anomalous primate" material, the study found only one sample of primate origin — identified as human — with the remainder matching known animals, overwhelmingly bears, alongside cow, horse, dog, sheep, goat, deer, raccoon, porcupine and tapir.[22] In 2019, the FBI declassified a 1976 internal analysis of hairs submitted by a Bigfoot researcher, which had concluded decades earlier that the sample was of deer origin.[23]
A separate and more controversial claim came in 2012, when veterinarian Melba Ketchum announced her laboratory had found genetic proof Bigfoot was a human-hybrid species. Unable to secure publication in a recognised scientific journal, the study eventually appeared in the "DeNovo Journal of Science" — a website registered only nine days before publication, whose sole issue contained nothing but this one paper.[24] Geneticists who reviewed the paper were sharply critical; Princeton's Leonid Kruglyak stated the analyses either returned entirely human results or failed in ways suggesting technical artefacts rather than any genuine novel species.[25]
Scientific consensus
Bigfoot's existence is not accepted by mainstream science.[1] Paleontologist Darren Naish has argued that if a breeding population of a large, undiscovered North American primate genuinely existed, several categories of evidence that are readily available for other rare megafauna would also be expected to exist for Bigfoot — consistent regional vocalisation patterns, physical tracks confirmed under expert scrutiny, and above all, confirmed DNA — and that the total absence of all three, rather than any one alone, is what makes the creature's existence exceedingly unlikely.[26] Cultural anthropologist Phillips Stevens has separately noted that maintaining any breeding population over generations requires a substantial number of individuals spread across a wide area — difficult to reconcile with the total absence of remains, fossils, or a single confirmed body.[27]
Not every credentialed scientist dismisses the question outright. Primatologist Jane Goodall, asked directly about Bigfoot in a 2002 NPR interview, said she was "sure that they exist," while also acknowledging she could not answer the fundamental objection of why no body has ever been found.[28]
Hoaxes
Bigfoot has an extensive documented history of hoaxes, acknowledged even by many believers as a significant and ongoing problem for the field.[29] The most elaborate recent case involved Rick Dyer, who in 2008 co-perpetrated a hoax involving a costume rented for the occasion, later admitting the fraud, before returning in 2014 with a second fabricated "Bigfoot corpse" — a $60,000 latex, foam and camel-hair prop he eventually admitted was manufactured to order.[30] A widely reported 2007 trail-camera photograph, presented by the Bigfoot Field Researchers Organization as showing a juvenile Bigfoot, was identified by Pennsylvania wildlife officials as an ordinary bear suffering from mange.[31]
Bigfoot subculture
A substantial, self-identified subculture has grown up around Bigfoot research, with practitioners often calling themselves "Bigfooters" or "Squatchers."[32] A 2026 study by sociologists at Cardiff University and the University of Sheffield, based on interviews with 160 Bigfoot enthusiasts, found the community skewed toward middle-aged white men, often with military or blue-collar backgrounds, and identified a broad split between "Apers" (who believe Bigfoot is an undiscovered biological primate) and "Woo-Woos" (who regard it as a supernatural or paranormal entity).[33]
