This spectacular formation is known as "the Nave" in Ogof Ffynnon Ddu, a cave inside the mountains surrounding Penwyllt in the Upper Swansea Valley, South Wales. I visited the formations with a few caving friends to photograph it. To reach the formations, we had to use SRT equipment. for non-cavers SRT (Single Rope Technique) allowed us to abseil down a series of vertical shafts to reach the formations, then return by climbing back up the ropes - again using SRT techniques.
