Creigiau Eglwyseg, near Llangollen, Wales

This is the superb western facing scarp of Creigiau Eglwyseg (Eglwyseg Rocks) near Llangollen, Wales. This is composed of Carboniferous Limestone (Dinantian). The lower foreground and the hill on which I was standing are comprised of Silurian slaty mudstones. A major fault line runs along the foot of the escarpment.
