While Finding Bigfoot was on location in Michigan, researchers recorded some strange sounds that they can't identify:
While in town for filming Finding Bigfoot members of the BFRO visited a site in central MI that had produced some interesting audio recordings. What happened next was captured on multiple audio recorders and witnessed by numerous people. The howls we heard were invigorating and spooky but what a cool night. I use a spectrogram and Audacity to show the audio. Who knows what it was because they moved away into property we could not enter. However, three of us spent the next couple of nights at the location and heard at least two more possible howls. Some of that trip was eventually seen on the Bigfoot and Wolverines episode of Finding Bigfoot along with vocals that had been previously recorded at the location. Thanks for listening and enjoy.
