Carningli -- periglacial block field

 


A great photo of the periglacial block field on Carningli Common, in the vicinity of Carnedd Fychan.  Posted by Val Colella on Facebook. This block field spreads over several square miles, and consists of a mixture of broken bedrock and glacial erratic boulders and slabs.   For much of the time you don't see it -- because the gorse, heather and bracken are too high -- but every now and again, burning clears some parts of the common and all is revealed.  Apart from the vegetation and the horses, this could be Greenland or the South Shetland Islands.  This type of block field is found in many Arctic and Antarctic landscapes on gentle slopes and plateaux.
