Looking south across the embedded cairn footprint towards Craig Berwyn, the southern summit (the cairn visible just below the crags) and Moel Sych, top right...

That is one large footprint, the topography arguably not sufficient to have caused serious slippage over the millennia?

The OS trig surmounting Cadair Berwyn (i.e the northern summit) can be seen rising beyond.

The truly monumental footprint, looking toward the northern summit cairn.

The monument quite literally sits upon the edge of the precipice, the cliff line falling to Cwm Maen Gwynedd far below. The ridge to the left, home to several enigmatic ‘mounds’, terminates at Mynydd Tarw

This view highlights the very extensive footprint.... Incidentally Arenig Fawr and Arenig Fach are upon the horizon.

And the reverse view, looking toward the summit crags of Craig Berwyn.

Sunburst approaching from Craig Berwyn (or the southern summit of Cadair Berwyn for those happy for a mountain to have two summits! – although I’ve tended to refer to it as Craig Uchaf). The northern summit (Cadair Berwyn (North) can be seen immediately beyond, with Cadair Bronwen deep in shadow far background.

A good representation of the cairn, I think. The onward route beyond Craig Berwyn to Cadair Berwyn is obvious.... in clear weather.

The cloud peels away...

Highlighting the extensive embedded footprint...... Craig Berwyn glowers beyond, with Cadair Berwyn subsumed within cloud to its left. Both summits feature a monument.

Approaching from Pen-y-Gurnos to the south........

Oo-er..... a ‘Crack in the Clouds’. The wondrous Moel Siabod rears across Dyffryn Mymbyr.

Certainly a long mound of some description...

The apparently ‘in situ’ stonework mentioned by Coflein...

Toward the black mass of Gallt-yr-Ogof...

Sunburst upon the mound. The Creigiau Gleision glower beyond.

Pen Llithrig y Wrach (right) and Pen Yr Helgi Du (centre) do battle with the cloud, beyond.

The hillfort [centre of image] as seen ascending Bryn Mawr from Bwlch-y-Groes, northern slopes of Moel Eilio. Llanberis is to the right.

I’ve attempted to indicate the approximate position of this wondrous little cairn circle located beneath the towering presence of Y Garn – viewpoint is Disgwylfa Fawr (with some optical assistance, naturally)

The well preserved southern cairn seen across the central. Y Garn rises top right.

Looking toward Nant-y-Moch from the massive, but unfortunately much-disturbed central summit cairn.

Approaching from the approx south.

Looking toward Y Garn from the southern-most of the summit cairns

Approaching Y Garn from Pen Pumlumon-Fawr.

The large summit cairn can be discerned in this image taken from Moel Eilio (albeit into the sun). There is another, smaller example surmounting the sheer cliff face of Craig Cwm-bychan nearer the camera, plus a number of other monuments residing upon the summits of The Nantlle Ridge rising above. The Lleyn Peninsular stretches away right background featuring hill forts, cairns and – oh – lots more.

Looking toward Mynydd Mawr and the Nantlle Ridge.... cairns, cairns, everywhere.

The summit monument has a very large footprint indeed. Yr Eifl, with Tre’r Ceiri perched upon its inner peak, can be seen centre skyline.

Moel Eilio possesses one of the most substantial muppet shelters I’ve seen in these Isles. But then it stands to reason, I guess. Lot of muppets to cater for.

Quite some footprint, even allowing for any slippage over millennia. Looking approx. north toward Anglesey.

Looking towards distant Tre’r Ceiri.....

Looking approx north toward the Mam Cymru.... Anglesey. Note the very extensive cairn footprint which I did not believe was substantially due to slippage. The orientation toward the coast is obvious and similar to the great cairn which still crowns Drosgl upon the northern Carneddau.

Snowdon rises beyond the cairns.....

Towards Tre’r Ceiri, top left, from the western cairn... the lake is Llyn Nantlle Uchaf.

The Snowdon Massif rises beyond the eastern cairn.
