'Mercantour, Tinée/Vionène: red schist.'
In a small area surrounding the confluence of Vionène and Tinée the purple-coloured bedrock amazes visitors. It is a schist dating from the Permian period, when the earth's atmosphere contained oxygen for the first time in its history, turning iron in minerals red. Beauty is not the only result, fertility as well: around perched village Roure it weathers into a rich purple soil. Photo Paul Smit.
