The Clipper Mills audio comes from a real nighttime recording made in 2012 by people whose truck broke down in the Sierras. They captured eerie, extended screams and howls that many Bigfoot believers think could be vocalizations from an unknown creature.
In July 2012, a group of people traveling through the Sierra Nevada near Clipper Mills, California had their truck and boat trailer break down on a remote road with no cell service. While waiting there late at night, they recorded a series of strange and loud vocalizations the so-called Clipper Mills screams. According to the original uploader, the noises began around 10 p.m. and continued even after the camera was turned off. Their dogs reacted strongly to the sounds.
The clip was originally posted online in 2012 and became one of the longer and more widely circulated alleged Bigfoot audio recordings. Enthusiasts and cryptozoology blogs pointed to it as unusual because the sounds don’t clearly match typical known wildlife like coyotes or mountain lions, and the extended length (over 15 minutes) set it apart from many other alleged encounters.
