THE CARBONIFEROUS ROCKS AT WORLD’S END in North Wales

At Worlds End, Carboniferous Limestone has created a spectacular landscape of west-facing escarpments, which rise to 450m in height, towering above Llangollen,  nearly 8km in length and rises in a series of steps, deposited around 350 million years ago. There are extensive underground cave systems, while the lead-zinc mineral deposits at Minera have been worked since Roman times.

To the east on Ruabon Mountain, the Cefn y Fedw Sandstone (Millstone Grit) overlies the Carboniferous Limestone and supports a large area of heather moorland. Further to the east are the semi-industrial landscapes of the Upper Carboniferous Coal Measures around Wrexham.
