About Carningli

The little mountain of Carningli dominates the landscape around Newport and Cilgwyn, and although it is only 347m ( 1,138 feet) high it is visible as a prominent feature from the north and east, and even from the south, for travellers approaching from Mynydd Preseli. From certain directions, the mountain looks like a volcanic peak -- and this is appropriate, since it is indeed an ancient volcano. But it is extremely ancient -- around 450 million years old, be be almost precise -- and its present-day profile gives us little guidance as to what it looked like when it was erupting. When the mountain was born, the area which we currently call North Pembrokeshire was part of a great ocean, the bed of which was buckled up and down and shattered by earth movements and mountain building over millions of years. There was virtually no life on land, and very little in the sea. We know that there were tens if not hundreds of volcanoes across a wide area, since dolerites and other volcanic rocks occur in virtually all of the high points of the landscape.
