We’ve received the following message and photos from Alan Bowring of Bannau Brycheiniog National Park Authority:
“I’ve spent some time this week in and around the limestone escarpment from Craig y Cilau east to the Clydach gorge, in the course of which I came across a recent rockfall affecting the quarried crag at Darren Disgwylfa at the northeast corner of Mynydd Llangatwg. The affected area is just south of the prominent stone pillar landmark of the Lonely Shepherd at about SO 2190 1434 and the scar resulting from the collapse of a few tonnes of rock is sufficiently large and fresh to be visible from the A465 in the vicinity of Gilwern. I’m aware this is a bouldering venue (see image 637 for example) so any group or individual heading there should be aware of the presence of new blocks and the potential for further falls.
“Limestone and dolomites of the Clydach Valley subgroup have been quarried here and the fractured and rubbly nature of certain beds (see image 0642 of a nearby section of rockface) frequently result in unstable sections of cliff.”
