PGF BIGFOOT FILM SITE MATHEMATICALLY PROVEN, plus More Season Two BLUFF CREEK FILM SITE PROJECT Videos

BIGFOOT'S BLOG
Late January 2012 Edition

YES ANOTHER BLUFF CREEK MEGA-ISSUE

Well, the PROOF is in, now without the slightest doubt: The PGF Site has been completely verified. Find below a mathematical proof displaying the correspondence between our site map of the location as it is today, and the 1971 Rene Dahinden "aerial" shot. This proof adjusted camera angle and compared prominent lasting landmarks using trigonometry and geometry. It was done by a practicing geologist. The conclusion?:

"Overall the geometry of Robert Leiterman, Rowdy Kelley, and Steven Streufert’s survey is a perfect match with the photo taken by Rene Dahinden of the Patterson-Gimlin film site. It's nice to see some actual hard science being applied to the field. The survey was really well done. It made it fairly easy to get accurate numbers. Now all we need is the DNA project to prove these things are real. :-)"

Documentation will continue next summer, but for now this should be pretty much the last major Bluff Creek blog entry here until then. A few more episodes of the video project will appear in the near future, along with an interview being planned with our mathematician, geologist Jamie Snowhorse.

I'm hoping to move on to a bunch of other topics that have been brewing in the background (for me) while taking up all of the Bigfooting world's time and attention in hopeless waiting and conclusion jumping--that's right, Bigfoot MindSpeak, DNA, ETs and UFOs, and BS. The latter, we hope you know, stands for "BlobSquatches," and many other things in the "Bigfoot Community."

Now, on to our main feature. As luck would have it, a fellow wandered into my bookstore one day. He lives in a  very woodsy area down in the redwoods, and his wife works there, so he has developed some interest in Bigfoot topics. It just also happened that he was a qualified Geologist, capable of doing  mathematical analyses of terrain and locations. I told him about our Bluff Creek PGF project, and he was fascinated. Herein we will use his pseudonym for his last name, for privacy.

Comparing the PG Site Survey with the Dahinden "Aerial" Photo.
by Jamie Snowhorse

Jamie Snowhorse who graciously did this
proof for the sake of Bigfooting history.

Out of all of the evidence for the existence of Bigfoot none is more compelling than the Patterson-Gimlin film. The film is the most studied and analyzed piece of evidence in the Bigfoot community. At face-value it is either a hoaxed video of a man in a suit or an actual creature. Over the years the original location has been highly debated with many different “X”s on the map and none seemed to fit perfectly. Only recently has the newest and most promising suspected location been surveyed and mapped with accuracy. The newly suspected site was surveyed by researchers Robert Leiterman, Steven Streufert, Ian C. and Rowdy Kelley in an attempt to put an end to the controversy. Over the years the site had become overgrown and was subject to hydrologic processes that eroded away at the adjacent streambed. The gravel bar in the film is now meters above the meandering creek. And 40 years of weathering has altered the gravel bar beyond immediate recognition. A photo taken by Rene Dahinden on the hillside opposite the creek shows an aerial view of the original film site. This photo clearly shows the same gravel bar where the PG film was taken. In the photo there are many distinguishing objects that would appear in a survey of the area. These objects are durable and static enough to withstand the test of time and maintain their original positions. The best objects to use as survey monuments are trees and stumps because they are immovable and their positions can be easily surveyed. The photo serves as an accurate record of the film site and It’s monuments. The survey of the suspected site by the researchers is mapped on a two dimensional plane consisting of an X,Y grid with ten foot spacing. The survey is accurate enough to trigonometrically determine distances between objects with an accuracy of a couple feet. It clearly shows the stream bed and sand slope of the evolved creek. The orientation of the creek and the overall geometry of the survey gives the impression of a direct match; that the survey of the suspected site is an accurate survey of the original Patterson Gimlin film site. Even though the site gives the impression that it is a match with the original survey site, further mathematical comparison is needed.

The survey site and the Dahinden photo can be compared geometrically to prove that they are a match. And the first step in that process is to determine the angle of the camera of the Dahinden photo. To do this, a line is drawn between two monuments in the photo. For ease of calculation this line should be perpendicular to the camera and be significant in distance. A line between monuments marked P and K is suitable.This is the line all calculations will be based on. A Third monument should then be selected to complete a triangle between them. The same triangle should be drawn on the site survey between the same monuments. Now that there are two triangles to compare, the actual distances between the monuments in the survey are measured. For an accurate comparison and to double check the trigonometry a calibrated ruler is needed. For the site survey this should be calibrated to the grids set out on the graph. For the photo the ruler should be calibrated so that the actual distance of line PK should be marked on the corresponding line on the photo and the ruler should be stretched to fit (in this case 10.4x10 feet or just 10.4).

Next the actual length of the sides of the triangle in the survey are trigonometrically derived. Then on the triangle in the photo, a line is drawn from monument V down to line PK forming two right triangles with respective 90 degree angles. This line should form a ray to the camera. This intersection is labeled Delta or “Δ” . Now using the calibrated ruler, the length of lines VΔ, ΔP, and ΔK are measured. The length of line ΔP should be transferred to it’s corresponding position on the survey to exact the location of point Δ. Then a line is drawn from point Δ to monument V to make a triangle that corresponds to photo. These triangles can then be compared and a camera angle derived. The equation used was:

Length(camera angle°/90°)=Measured length on photo

With this equation, an approximation of the camera angle is derived. Therefore, if the actual length of line ΔV is 12.8 and the measured length is 3.7 then the approximation of the camera angle is about 26 degrees. This camera angle can then be used to find objects seen in the photo and objects documented in the survey. If the monument’s actual position corresponds with the measured position on the photo then the survey location and the photo location are a match.

Now that the camera angle has been derived, it is used to predict lengths that would appear in the photo.

Based on a camera angle of 26 degrees the prediction of the length of line AK in the photo at 5.37. When the photo is measured with a calibrated ruler the measured value is about 5.2 which is very close... within 2 feet. This proves that the geometry in the survey correctly matches the geometry of the photo. Even more objects can be compared this way to determine their corresponding locations. It is easiest to use the same calibrated line PK to base the trigonometry off of. Next, the position of monuments U, X, and F are exacted. Their positions were verified with an accuracy of about two feet.

Overall the geometry of the survey is a perfect match with the photo taken by Rene Dahinden of the Patterson-Gimlin film site. From this survey, accurate positions in the film of the alleged creature can be exacted which could prove to be useful to determine further information about the film and it’s subject.

THE BLUFF CREEK FILM SITE PROJECT, Current Members and NEW Videos

Rowdy, Film Producer, Adventurer, the most recent member
of our group, whom we met when he was working for
Animal Planet during the local FINDING BIGFOOT filming.

Me, you probably know me all too well.
Bigfoot nerdiness started this PGF obsession, but
at least it came to something REAL in the end.

Robert, State Parks Ranger in the Redwoods,
long-suffering videographer and video editor, he is the one
who forced Ian and me to actually document this stuff.

Ian C., in partial retirement, well OK, total Bigfoot retirement, at least for now.
Ian was a founding member,along with myself, of this obsessive  pursuit.
We still don't know if he has seen the site geometry proof yet. Last we heard
he had had enough of California and gotten lost in the mountains of Virginia.

*******

If there is going to be a BIGFOOTERS OF THE YEAR award, it should go to all four of us, not just Robert and me. Thank you to Daniel Perez and BIGFOOT TIMES for the honor.

Yep, we're not bragging. We just want to share the information, as always.

ANGRY BIGFOOT SPEAKS!

What can me say? I show hu-man guys to film site many time, they just no see. Now they get award, and what I get? Bunch of survey flags on my home turf. It not funny. When Bigfoot get award? I the reason you all out there on snipe hunt. Me make you famous on hu-man TV, and I not even get cameo role? I start think again go back to eat hu-man and dog, be monster again and not care. No more Mr. Nice Bigfoot, me say.
