THE STORY
Reported Haunting
Moaning Caverns combines an naturally eerie acoustic phenomenon, ancient human remains and longstanding reports of voices, shadows and other unexplained activity.
Moaning Caverns is a large natural cave system in California's Sierra Nevada foothills. The cavern takes its name from an eerie moaning sound once produced by air moving through the cave. Human remains discovered within the cavern indicate that people died there long before its modern development as a tourist attraction. Over time, visitors and paranormal enthusiasts have also reported unexplained voices, shadowy figures, cold spots and the sensation of being watched. These paranormal claims remain unverified.
