Conglomerate (gravelstone) outcrop on the side of the road with fantastic views of a landscape of folded and fractured rocks The area around Aill Dubh is made up of sedimentary rocks, such as sandstones and conglomerates, that also formed when the ancient ocean was closing 480 million years ago. There is a superb outcrop of these sandstones and conglomerates along the road around Aill Dubh, where you can also see red granite cobbles within the otherwise grey rock colour. There are also layers of volcanic ash that stand out as dark cliffs on the mountain slope. Whilst exploring our geosites, remember to follow these simple principles to help keep our beautiful landscape spotless and to preserve it for generations (those living here and those visiting here) to come.
