Analysis of 1967 Patterson-Gimlin Film by the North American Science Institute
The 1967 Patterson-Gimlin Film, photographed on October 20, 1967 in Bluff Creek, California by Roger Patterson and Bob Gimlin is one of few pieces of photographic imagery that has not yet been proven to be a forgery. This film was evaluated by the author to see if it may be excluded from the set of Bigfoot phenomenon observations by demonstrating it is a forgery.
Highlights: (2:44+) Mathematical analysis (ratio using pixels and a known height) assigns a height of 7' 3 1/2" (plus or minus one inch) to the figure in the film. (3:24+) The figure's waist is calculated as 81.3 inches (3:38+) The figure's chest perimeter is calculated as 83 inches (4:33) The figure's arm length is calculated as 43 inches (4:48) "The arm length of the subject is 5.5 standard deviations from the human mean which is in the 99.9999981 percentile or is present in one out of 52.5 million people." (4:58) The subject's leg length is calculated as 40 inches (5:19+) Morphology, or appearance, of the subject's hand, foot, and face all put it between the human and gorilla in Glickman's opinion. (8:00) "There are several ways the subject may be differentiated from traditional forgeries: non-uniform hair texture, non-uniform coloration, and non-uniformity of hair length." (8:17) "The appearance and sophistication of musculature as seen in the Patterson-Gimlin film has not yet been reproduced in costumes in the entertainment industry." (9:40) Differences between the human knee cycle and the figure's knee cycle. (10:15) Discussion. "To date the Patterson-Gimlin film has defied explanation, and it continues to do so after three years of rigorous forensic examination."
