More caving in Ogof Ffynnon Ddu (OFD), South Wales

OFD cave at Penwyllt, near Abercrave in South Wales.

These pictures were taken in the 'Escape Route' of OFD 1 which is the lowest of three entrances into the cave system, the entrance being at the base of a very steep hill.

Just click on any picture to see it larger.....

The flat, wet floor seen here, is called 'flowstone'. It looks like a rough concrete floor, but is actually stone. It has been formed this way by sheets of water flowing down the rock walls and washing over the floor, smoothing the surface over thousands of years, washing particles over the rock 'sanding' it down and depositing minerals.
