Case files — Bigfoot / sasquatch (North America)

Scope note, and why this file breaks the pack's own rule. 01-methodology.md weights this pack against the United States on the grounds that the US already has a very large English-language literature of its own. This file is the deliberate exception, and the exception is not a concession to popularity. Bigfoot is the only cryptid here whose record is institutional in three separate registers at once — statute (Washington counties, 1969–1992), federal forensics (the FBI hair examination, 1976–77), and a documented hoax economy that its own investigators wrote down. It is also the only one with a dated fossil candidate that a peer-reviewed journal has now delimited.

Canada carries the non-US weight this pack normally insists on: the word sasquatch is Canadian, and the only legal answer found on it in Canada is provincial and negative (2).

Compiled 25 September 2026. Everything here is sourced to sources.md; nothing here asserts that the animal exists. Where a test exists, the result is printed in the section that reports the claim.


1. Ape Canyon, Washington (1924) and Bluff Creek, California (1958) — the two founding events

Rating: D (the 1924 episode was checked and dismissed within weeks; the 1958 tracks are admitted by the family of the man who is by most accounts behind them) · Status: the word is the road crew's, made famous by a newsroom

1a. Ape Canyon, Mount St. Helens, Washington — summer 1924

1b. Bluff Creek Road, Six Rivers National Forest, California — 27 August 1958


2. Chehalis / Harrison River, British Columbia, Canada — 1929 — the word sasquatch

Rating: B (documented: a published magazine article and a scholarly reading of it) · Status: the name is an anglicisation; the beings it flattens are not one animal


3. Skamania County, Washington — 1969 and 1984; Whatcom County — 1992 — the ordinance

Rating: B (documented: ordinances and a resolution, with a publication affidavit) · Status: the paperwork is real; the animal is not — and the law says why it was made


4. Bossburg, Stevens County, Washington — 24 November 1969 → 1970 — Cripplefoot, and the market it created

Rating: C (reported) with a documented hoax layer around it · Status: the best casts in the corpus, found by a man who then tried to sell a film of the same animal


5. Skookum Meadows, Gifford Pinchot National Forest, Washington — 22 September 2000 — the body cast

Rating: D — the artefact was examined and the best-supported reading is an elk · Status: explained, and explained by the animal whose tracks were all over the site


6. Myakka River, Sarasota County, Florida — December 2000 — the letter to the sheriff

Rating: D (unresolved artefact, improbable as described) · Status: an anonymous mailing to a law enforcement agency, and the arithmetic does not close


7. Newberry County, South Carolina (2 November 2024) and Voluntown, Connecticut (5 July 2026) — two reports the BFRO called credible

Rating: C (reported, with the reporting machinery visible) · Status: two reports that reached the press mainly because of who filed them


8. Southern China — Gigantopithecus blacki — the candidate, delimited in 2024

Rating: A (peer-reviewed, dated, and it removes the folk hypothesis) · Status: the only fossil ape of the right size and time, and it is both the wrong size of window and the wrong hemisphere


9. Bluff Creek, California — 1967, examined again in 2026 — "Capturing Bigfoot" and the reel from the safe

Rating: C (documentary evidence, contested) · Status: a 59-second film whose provenance chain has a new hole in it, and a special-effects counter-claim on record


10. The register itself — 75,000 reports, 5,500 kept, one state with none, and one day of the year

Rating: B/C (the organisation's own published counts, and the press that repeats them) · Status: the volume is the most real thing in this file, and it is produced by a filter, not by a survey


What this file does not claim

  1. Nothing here has been verified by science. No specimen, no tissue, no photograph under controlled conditions, no repeatable measurement, in any of the ten sections.
  2. The best physical evidence in the corpus has a mundane reading attached to it in the same locality. The Skookum cast returned elk hair and elk tracks (5); the Cripplefoot track line came from a town whose record includes a mine-shaft sasquatch and a freezer foot (4); the founding tracks were admitted by the hoaxer's family (1).
  3. The named fossil candidate is now bounded — Gigantopithecus blacki is dated to an extinction window of 295,000–215,000 years ago in southern China, from 22 sampled caves (8). That is a result about Asia and the deep past, and it closes the most respectable version of the claim rather than opening it.
  4. The volume is the phenomenon. By the organisation's own 2023 account nearly 75,000 reports have been filed and 5,000–6,000 kept as credible; its public database lists 5,769 from US states as of September 2026, 98.8% of all its listings, and has never recorded a report from Hawaii. Volume at this scale is produced by a filter and a culture, and it is not the same thing as a population.
  5. The word itself is a translation, twice over. "Sasquatch" is a schoolteacher's anglicisation of se'sxac published in 1929 against the stated preference of the elders in the account (2), and "Bigfoot" is a road crew's nickname that a 1958 newspaper printed as one word (1). Both names travel better than the beings they replaced.
