- A hillwalker spotted what looked like a giant “hole in the mountain” above Abergynolwyn in North Wales, prompting online speculation ranging from old slate mines to WWII plane crashes to dragons and government black holes.
- The feature sits in the Dysynni Valley, an area with rich mining history and nearby historic crash sites, though none match the location of the supposed “hole.”
- The region is known for striking shadow phenomena and ancient archaeological sites, adding to the mystique surrounding the odd visual effect.
