Why has the Forest of Dean been placed with North Wales?

You may be asking, why has the Forest of Dean been placed with North Wales instead of South Wales? The reason is because there are far more opportunities to find cryogenic cave calcites in South Wales than there are in the Forest of Dean. Those caving in South Wales would therefore have an unfair ad...

What should I look for and how do I find CCCs?

FORMATION Cryogenic cave calcites (CCCs) form when water enters a cave and turns to ice. As the water freezes, it becomes increasingly enriched in ions to the point of supersaturation and precipitation of calcite. Today, caves in Britain do not contain ice, but evidence that they once did can be fo...
