Dent & Ingleborough from the limestone pavement at Newbiggin Crags
Ingleborough (far right) and the hills around Dent seen from the cliffs of the limestone pavement of Newbiggin Crags, South Cumbria. The foreground clint features an extraordinary pattern of dendritic and centripetal drainage runnels in formation.
Limestone pavements were formed during the last Ice Age in the Pleistocene period when moving glaciers scoured bare the surface of the underlying limestone bedrock. The classic pattern of clints (blocks) and grikes (fissures) was produced by the erosive action of overlying soil - such as the moraine deposited by the glacier - and the rainwater that permeated it, enlarging the natural faults in the limestone rock.
