The Lights and the Dark Shape on Presque Isle Beach

Late on 31 July 1966 a party whose car was stuck in the sand at Presque Isle State Park, near Erie, Pennsylvania, saw a bright light drop to the beach and play a ring of lights over the sand. Later a teenage girl in the car saw a dark shape bigger than a man lumber into the bushes. Investigators floated a raccoon, a bear and a hoax, and Project Blue Book listed it Unidentified, writing that there was as yet "no explanation of the lights". This is the record of what the party reported, not a verdict on what came down on Beach 6.

◆ THE SHORT VERSION

  • The Lights and the Dark Shape on Presque Isle Beach is a reported UAP case in Beach 6, Presque Isle State Park, near Erie, Pennsylvania, USA, 31 July 1966, about 22:23-22:30 EDT.
  • A party stranded on a Presque Isle beach on 31 July 1966 reported a bright light that tumbled down, stopped five to ten feet above the sand and settled with a hum while their car vibrated.
  • A sixteen-year-old girl in the car reported a dull black shape larger than a man that lumbered into the bushes when she blew the horn.
  • Investigators variously suggested a raccoon, a black bear and a possible hoax, yet Project Blue Book listed the case Unidentified (#10798) and wrote that there was as yet "no explanation of the lights".
  • Triangular marks in the sand were cast; the Flight Dynamics Laboratory found them asymmetric and unlikely to be landing supports, and radioactivity was negative.
  • For this case Fractured Realities holds 2 distinct sources, 1 corroborating primary document and 4 distinct claimants on its resolved list.
  • The archive grades it L4 · OFFICIAL RECORD — a released government record names who saw it, the top of our scale, though no independent testimony sits beside that record.

Counts are resolved totals of what sources say, computed 2026-10-12; the reported details above are claims in the record, not findings. A record of reports, not a verdict on what happened.

The car was stuck in the sand on Beach 6 at Presque Isle State Park when the light came down. It was about 22:25 on 31 July 1966. The party saw a bright light "free-fall", tumbling like a cube or a hexagon, then stop five to ten feet above the beach and settle with a hum while the car vibrated. A ring of lights played over the sand and the trees. When a patrolling police car arrived the lights went out. A teenage youth walked up the beach with the police. In the car a sixteen-year-old girl then saw a dull black shape larger than a man. It lumbered into the bushes when she blew the horn. The Blue Book file names one adult in the party, Anita Haifley, aged 22.

What is on the record

Project Blue Book holds the case as Unknown #10798. Triangular marks in the sand were cast. The Flight Dynamics Laboratory estimated 750 to 1,000 lb for the larger marks but found them asymmetric and unlikely to be landing supports. The soil held urine and lacquer resin, and radioactivity was negative. One investigator suggested a raccoon, another a black bear, a third a possible hoax. Blue Book noted many discrepancies and raised Arcturus for the first "star" the party saw. It found no link between the light, the marks and the creature, and still wrote: "As yet, there is no explanation of the lights that were observed." The case is listed Unidentified.

Blue Book gives 31 July, but a Flight Dynamics memo says 30 July and one investigator's report gives 1 August at 0025Z. The CIA's reading room holds a reprinted magazine account dated 1 August that names the park patrolmen as Ralph E. Clark and Robert Loeb Jr. It is press reporting, not a CIA evaluation. NICAP, Berliner's list of Blue Book Unknowns, Hatch and Johnson carry the case.

Why it sits where it does

L4 · OFFICIAL RECORD — a released government record names who saw it. Haifley and the two patrolmen are the identified adults. The two younger witnesses were minors and go unnamed. The archive holds no account from outside the file, and the investigators themselves split between an animal, a hoax and no explanation at all. The grade reflects sourcing, not whether the report is true. What fell onto Beach 6 is not resolved here.
