The Gwynedd Archaeological Trust (PRN5546) cites several structures in upper Cwm Cowlyd as the remains of prehistoric ‘scattered hut circles’....
Unfortunately I arrived in the vicinity (on my return from Pen Llithrig y Wrach) with darkness fast drawing in, not to mention being subjected to vicious hail fronts moving down the cwm with ever increasing frequency.... hence just the one image at an extreme exposure limit, I’m afraid. I believe what I’ve captured is one of the hut circles, but a return visit is necessary to confirm this.
