The folks who staged the Patterson-Gimlin hoax came forward a few years ago for interviews. It’s fake, sorry to say.
Two guys on horseback running across a lone Sasquatch in the wash of Bluff Creek, Ca., east of Eureka, Ca. does push the bounds of believability past the breaking point. However (and there is always a however) Patterson was up there sniffing around because a logging company construction crew in the area were reporting odd occurrences around the construction site. The 52 gallon drums of diesel were being found down the side of the hill in the mornings, with "large" footprints all over the place.
I guess if a couple of lunatics decided to put footprints around a construction site, push around a bunch of oil drums weighing at least 440 lbs out in the middle of nowhere. Then there was the 700 lb. grader tire they found over in a ditch one morning.
I've been up there a few times. It's very sparsely populated, steep mountainous country that people drive thru, not a destination of any kind. All these events took place several miles up a logging access road off the two-lane highway. People who lived up there had better things to do, like make a living - especially in 1958.
False.
The ones claiming the patterson footage was staged were themselves debunked.
