Berry-laded Midland Hawthorn growing in limestone pavement at Farleton Knott
Berry-laded Midland Hawthorn (Crataegus laevigata) bushes growing in the narrow grikes of the limestone pavement of Farleton Knott in South Cumbria.
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.
