Shadows play across Parkhouse Hill, making the rocky pinnacle stand out from the surrounding hills in Dowall Dale, Staffordshire. At the hill’s western end there is a sharp pinnacle that appears almost separate from the main limestone reef. Formed when this area of the Peak District was at the bottom of an ocean, the harder core of rock has been revealed by the gradual erosion of softer outer layers. A spring bubbles up from near Dowall Cave and flows through grazing pastures on its way to join the River Dove. In spring the brook swells with extra rain running off the hillsides and floods across the surrounding grassland.
