Looking approx south toward Y Mynydd Du crowning the skyline...
The south-western end of the ridge: can’t argue with that.
The southwestern bank from without – not particularly powerful, but then, given the topography..
Looking along the spine of this delightful ridge to the south-west... the southern flank is sheer, so no need for any defences there.
Retrospective to the northeast... one can appreciate what certainly appear to be defences within the copious fern (I attempted a definitive look but was driven back by industrial-strength bramble within the greenery).
Viewed across Cwm Brefi from the monument crowning Crug
Cairns as far as the eye can see.... Bryn Rhudd is to the left of image, with Cnwch Mawr approx centre and Banciau Duon far right.
Looking across Cwm Brefi to the excellent Banc-y-Gwyngoed and complex upon Bryn Rhudd. Yet another very substantial (unmarked) cairn may just be seen upon Cnwch Mawr, centre right
Looking approx south towards the wondrous Carn Fawr and Craig Twrch etc...
Looking from the southern flank of Gurnos (near Craig y Mynach) to the approx north-east and highlighting the splendid Nant Paradwys... all kinds of excellent prehistory to be seen by following that there track..
Looking towards the site of the Rhos-y-Gelynnen stone row
Having incorrectly assumed the cairn would crown the ‘summit’ of Gurnos... I then incorrectly assumed it would be located upon one of the radiating rocky ridges... but no.
Clearly the remains of cist/chamber of some description.
Quite a lot of internal structure is still evident for such an obscure site...
Looking approach SW towards a quartet of other Bronze Age cairns.
Looking across the monument into the fastness of ‘The Green Desert of Wales‘
From this angle, the prehistoric ancestry is pretty obvious.... Llan Ddu Fawr rises beyond. This is a fabulously obscure, wild area.
The ‘marker cairn’ sitting upon the (probable) prehistoric footprint. Bryn Dafydd lies beyond.
The summit ridge looks rather benign from the Cambrian Way. Don’t be fooled like a muppet.
The seriously overgrown summit – just the thing for that hayfever
The ‘post’ is presumably the remnants of a long since demised tree.
A good way to start the day, fresh – or not so fresh – from the long drive from Essex.
Main monument from the northern...
