What is recorded here

Pollderreen is a recorded cave place in County Clare, Ireland, where a ten-foot canyon passage cuts through limestone and soft dripstone coats the walls near the surface. The water flows from a northern swallet to a southern pot, marking the limits of its hidden drainage basin. Explorers entered the cave in the twentieth century and followed the stream to a sump beyond a thousand yards, revealing a chamber system shaped by joints and shale. The cave remains a quiet witness to rain, rock and human curiosity, its depths still holding more than measurement can capture.
