READ: Hundreds of Mysterious Speakers Found Screaming Near Mount Shasta

Karrie Ann Snure and her daughter Jordan were riding near Highway 97 in Weed, California, when they heard an eerie screeching noise coming from off the trail. Following the sound, they reportedly found somewhere between 100 and 200 solar-powered Bluetooth speakers scattered across a hillside and planted in the ground. When heard together, the speakers created a chaotic mixture resembling static, screaming, and electronic noise. Listening to individual speakers revealed something even stranger: some appeared to be playing spoken recordings, including what sounded like a sermon and a repeating voice in which the word “salvation” could reportedly be heard.
