I apologize if this article has already been posted.
I will have to track those studies down. Not, of course, that any anthropologist takes another’s conclusions at face value. Like, what fun is it if we can’t have pissing contests in letters section of The American Anthropologist? 
An update to this thread 21 years later:
The Famed 1967 Bigfoot Film Was an ‘Incredible Hoax,’ Says the Director of a Groundbreaking New Documentary: The new doc ‘Capturing Bigfoot’ offers up some startling new revelations behind the story of Sasquatch, thanks to film footage locked away in a safe for decades

Evans had the 16mm film [which was sent to him] developed and days later found himself looking at a 40-second clip set in a location similar to the one in the 1967 movie, showing what appeared to be a slightly skinnier-looking Bigfoot walking into the woods.**
“It took me maybe nine months to realize what we really had,” says Evans, who was able to determine, by markings on the film, that the footage had been shot in 1966, roughly a year before the now-famous clip in the 59-second Bigfoot movie was allegedly shot. “What we eventually found out is that [this new footage] represented a trial run, a rehearsal that was never discarded.”**
You know, the forum has had a few threads discussing Bigfoot over the years, made difficult to search for because we have/had a member called Bigfoot…
There have been questions, if not outright allegations, of fraud for many years. Check out this Wiki Article: Patterson–Gimlin film - Wikipedia
It’s odd that no trailcams have caught the monster.
I’m reminded of a coworker who swore to the existence of BF, because his son, who lived in Washington, said they were seen all the time. Also, he never understood that an admonition about hunting them which was printed on hunting licenses or driver’s licenses or something was in jest.
