Two teenagers have sighting east of Seneca

In the summer of 1979 the witness and a companion had pulled off the road east of Seneca when they heard a loud shrieking growl. A large human-like animal approached their vehicle in bounding steps. The witness shouted for the companion to get in, locked the doors, and fled at high speed, remaining frightened and avoiding that road afterward.

The Database of Unexplained Encounters. Claims are recorded as claims: the Anomadex catalogues what people reported, where it was reported, and how sure I am that it was read correctly. It does not rule on what they saw.

A quick ask from the person behind the Anomadex: if you allow analytics, Google Analytics shows me which places, phenomena and searches you're most curious about. That tells me which regions and sources to add next and what to make easier to find. It never sees your name or anything you send me, and nothing is set unless you say yes. Privacy
