Meanwhile, in the Brecon Beacons

Thanks to Phil for 4 images of the cirque called Craig Cerrig-gleisiad (glitter-stones crag) in the Brecon Beacons.The top one looks south into the Taff Valley; the second one looks out of the cirque, over the lip, towards Brecon and Hay on Wye in the distance; the third looks into the cirque, with the headwall in the distance.  The last photo, below, shows the inside of the cirque with Pen y Fan and Corn-du in the distance.

There are some very spectacular glacial features in the Beacons, all well recored and studies over the years. The ice divide in this area seems to have been very mobile -- apparently shifting about in all compass directions during the course of the Devensian.
