This is the official designation and classification of reports submitted to the MABRC, and as such, efforts should be made to stick with this classification procedure as possible.


  • S – Single sighting or observation, one Bigfoot seen
  • SM – Observation of multiple Bigfoot
  • H - Hair
  • T – Single Bigfoot track
  • TM – Multiple Bigfoot tracks, but not from the same individual
  • TT – Multiple Bigfoot tracks of the same individual, a track way
  • P – Photograph, manned or unmanned, still or motion, film or digital
  • A – Audio recording of a Bigfoot
  • O – Detected odor
  • V – Vegetation disturbance, such as browsing, tree twists, etc.
  • N – Nest or beds
  • F – Fecal matter
  • L – Lore, indigenous oral traditions, historical references
  • B - Audio Heard
  • DK - Deer Kill
  • R - Rock throwing
  • W - Wood knock
  • 1 – Single observer, no collected evidence
  • 2 – Single observer, collected evidence
  • 3 – Multiple observers, no collected evidence
  • 4 – Multiple observers, collected evidence

As an example if a group, say XBO, has three of its members find three different sets of Bigfoot tracks, photographs them and casts them on 1-12-06 in Bend Oregon, you could designate the observation as TM4-XBO-1-12-2006-Bend-Or. This would be better than trying to describe the event with the sentence above. All multiple track finds could be searched with the later designation.

When submitting a sighting report to the MABRC, this is the classification system we use for sighting reports.

This is based on a recommendation by Rick Noll to better classify Sighting Reports
