Caption: A dry valley, Park Farm, Cheadle Park, Derbyshire.
Description: Looking south-east, 150 m. east of Park Farm, Cheadle Park. A dry valley in Triassic sandstone, Cheadle. The valley is excavated into Triassic sandstones. The gravelly soil in the left foreground is on the side of a disused gravel-pit working the conglomeratic Freehay Member of the Hawksmoor Formation, which caps the hill down to the base of the bracken-covered part of the slope. The valley is believed to have been carved under periglacial conditions where the permafrost rendered the ground impermeable and to have been left dry by a falling water table following the melting of permafrost. Gravel workings on the horizon are also in the Freehay Member, while the intervening low ground is underlain by partially drift-covered Carboniferous Coal Measures rocks.
