Burn marks and ghostly handprints have been reported on vehicles, while urban explorers claim to hear voices and screams from the surrounding woods. The site continues to draw thrill-seekers and paranormal investigators, with multiple YouTube investigations capturing unexplained lights and EVP recordings.
