This is a still frame from what is called the Patterson Grimlin film.  It was shot in 1967 in northern California.  This I believe is a real picture of a Bigfoot.  Why would I say that this is real and not a hoax?  I will outline several reasons why I think it is real.  

• I would like to remind you that we think with the technology we have today.  Think back to what was cutting edge in 1967.  Planet of the Apes was around the same time.  The faces were plastic and unbend able.  They put clothes and shoes on them because they were unable to make the costumes realistic enough.
• Now look at the picture above.   You see breasts and muscles on the figure in the picture.  Who could and would be able to do this in 1967?  It was not discovered until later that this was female.
• Look at the arms.  How would you fake the length?  The swing and movement is natural and not floppy like what you see in other hoaxed videos.
• The hair is not uniform on this figure either.  Not what you see with gorilla costumes or hoaxed pictures/videos. 
• One of the most compelling reason why this is real is our technology.  We have used our advanced technology on this film.  The modern technology has enhanced and showed more details of the figure.  I would expect the opposite.  The best example to emphasize this point is our old movies shown with our modern technology.  They still look old and the new technology just shows the flaws.  

For me this is one of the most fascinating and compelling film that caught a female Sasquatch walking across a creek bed.
