The shark's fin silhouette of Parkhouse Hill in England's Peak District National Park, is a stunning sight. This limestone peak, together with that of its neighbour Chrome Hill, make up in drama what they lack in height. The range of hills here in the upper Dove Valley of Derbyshire - High Wheeldon, Hitter, Parkhouse, Chrome and Hollins Hills, were formed from coral reefs in a shallow tropical sea 360 million years ago. Now the long dead sea creatures can be seen preserved as fossils in the limestone.

It is an extraordinary place - a favourite place, somewhere I go back to time and time again. It is always different and never fails to inspire.
