This recording published Aug 13, 2012 on YouTube by Bigtoetime, was made on July 8th, 2012 in the Sierra Mountains near Clipper Mills, California. The creators of the video make jokes about ‘sasquatch,’ but apparently they really had no idea at the time ‘what’ they were hearing, except that it wasn’t anything they’d ever heard before.
Some have speculated the sounds might be amplifications of bear cries, or wild dogs or coyotes. Others suggest they are animal cries which seem more ‘ape-like’ than ‘bear-like,’ and are certainly not those of a mountain lion, etc.
Whatever happened, the folks who recorded the eerie incident, a disturbance that lasted for almost half an hour, while they waited in their broken-down truck along the dark roadside, were fairly unnerved by it, as were their dogs.
You be the judge.
