The limestone pavement of Farleton Knott juts into the sky
The incredible sheet of inclined limestone pavement known as Farleton Knott in South Cumbria. The summit affords breathtaking 360 degree views encompassing Ingleborough to the east, the Cumbrian mountains to the north and Morecambe Bay to the west. Remarkably, prostrate native Midland Hawthorn (Crataegus laevigata) bushes thrive atop the bare rock and on this glorious day in early Autumn, glowing red with a mass of berries.
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.
The inclined pavements of Farleton Knott form a 'karrenfeld' - a solid sheet of ice-scoured limestone dissected by few grikes.
