The Story

Indigenous traditions across the Pacific Northwest describe giant hairy forest beings long before the term Bigfoot. The modern era began with 1958 footprint casts in Bluff Creek, California, and the controversial 1967 Patterson–Gimlin film. Thousands of reports, track casts, and audio recordings exist, but no specimen has been verified by science.

  • The 1967 Patterson–Gimlin film showing a bipedal figure with apparent breast tissue and long arms.
  • Thousands of footprint casts with dermal ridge patterns argued by some analysts to be non-human.
  • Consistent cross-cultural descriptions from Salish, Kwakwaka'wakw, and other First Nations traditions.
  • No body, fossil, or DNA sample accepted by mainstream primatology.

Unresolved

What We Still Don't Know
