I am not sure what to think about the “growl” in Hellfire Caves. I do have to say, if there was a creepy place I wanted to visit and maybe stay for the night, this would be it. Demonic rituals, unexplained events, and even an alter where they performed satanic rituals directly beneath a real church. Sounds like the beginning of a Horror movie, but it is real.

didn’t really sound like a growl to me. In fact had the video not repeated itself I would not have known there was something there. It seems to me like it could have been some ambient noises from elsewhere in the cave/cavern/tunnel.
