Underground Section
The entire river runs underground for 1/4 mile at Porth yr Ogof as it crosses the Carboniferous Limestone outcrop. It resurges at the Blue Pool. There are fifteen known entrances to the cave system which is also known as 'White Horse Cave' after the supposed resemblance to a horse of a flowstone feature near its main entrance. It is a complex maze of passageways, large and small, mostly developed along one or two major bedding planes. In extreme flood conditions the entire cave can flood to the roof. It is used heavily by school and adventure groups though sections of the cave can be hazardous for the unwary. There have been a number of fatalities over the years.

Famous quotes containing the words underground and/or section:
“Political correctness is driving machismo underground and recalling effeminacy from exile.”
—Mason Cooley (b. 1927)
“The demonstrations are always early in the morning, at six o’clock. It’s wonderful, because I’m not doing anything at six anyway, so why not demonstrate?... When you’ve written to your president, to your congressman, to your senator and nothing, nothing has come of it, you take to the streets.”
—Erica Bouza, U.S. jewelry designer and social activist. As quoted in The Great Divide, book 2, section 7, by Studs Terkel (1988)
