This enigmatically located cairn sits upon Esgair Garn overlooking the extreme eastern limit of Llyn Brianne. The monument is liberally ‘sprinkled’ with quartz....
According to Coflein (OS 1977) it is:
“..15.9 m in diameter and 0.9 m high at the centre, where a modern cairn adds 0.6 m of height. It is noteworthy that the majority of the stones forming the cairn appear to have originally been particularly selected for their varying quartz content. An obvious outcrop of this material was not observed in the immediate area around the cairn”.
It is possible to park upon the verge of the minor road forced to make a major loop around the reservoir, where upon a short scramble to the east will allow the traveller to contemplate the significance of quartz at close quarters. Intriguing.
