UNEXPLAINEDCRAFT
The Lake Cote Photograph
1971 · Lago de Cote · Costa Rica
WHAT IT IS
Captured automatically by a government mapping camera at altitude — no witnesses, no obvious hoax. One of the most credible photographic cases on record.
THE CASE FOR
An automatic government mapping camera photographed it from altitude with no human in the loop to hoax it, and independent analyses found the image consistent with a real object over the lake.
THE CASE AGAINST
It is a single frame with no witness sighting to anchor it — a film-handling defect or water-surface artefact is hard to rule out from one exposure.
WHERE IT STANDS
Unexplained. No identification has been established. The record leaves it open.
