Caving

An ailing American explorer trapped 3,000 feet deep in Turkish cave awaits difficult rescue

Rescuers from across Europe rushed to a cave in Turkey on Thursday, launching an operation to save an American researcher who became trapped almost 1,000 meters (3,000 feet) below the cave's entrance after suffering stomach bleeding.

Up to a third of Slovenian caves polluted

Slovenia has a rich underground world with caves large and small dotting the country. They have attracted cavers, visitors and researchers from near and afar for centuries, but also people who used them as a handy way to dump their waste. As a result, 20-30% of Slovenian caves are now thought to be polluted and cleaning them is a major challenge.
