Limestone pavement above the town of Ingleton in North Yorkshire protrudes from grassy moorland. The unusual rock formation is caused by glacial erosion, the deep cracks are referred to as grikes and the flat areas of stone are called clints. Inglebrough and Whernside mountains loom beyond a lone Hawthorn (Crataegus monogyna). Stratus cloud hangs above the peaks, golden light near sunset contrasts with the blue grey sky.
