A named place photographed at this map point in Powys.

Cliff over Grwyne Fawr Reservoir consists of Silurian-age volcanic and sedimentary rocks, formed around 430 million years ago during ancient volcanic activity and subsequent deposition in a shallow sea. The area is notable for its well-exposed geological sections that provide insights into the volcanic history of the Welsh Basin.
