This is a deceptively substantial upland cairn which, to my mind, should be taken as a pair with the splendidly sited ‘Blaneau-draw’ monument a little way to the ENE. Indeed, an approach from Cwm Sorgwm, via the latter, makes for a grand hill walk with some excellent views. I was able to park upon the verge just south-east of the farm access road’s junction with the ‘main road’ through the cwm (which, incidentally, is a good starting point for an ascent of Mynydd Troed’s cairn).
Anyway, according to Coflein what we have here is:
“A mutilated cairn, 23m in diameter and 1.8m high, surmounted by a modern cairn. Set on the crest of a mountain ridge, on the boundary between two communities”. [J.Wiles 15.08.02]
