Weekly Photo Challenge: Layers

Dartmoor in Devon is a National Parkthat has lots of exposed granite hilltops or Tors. The rock dates back to the carboniferous period and thrust through the surface around 280 million years ago. a variety of mineral ores have been extracted for centuries. Now we can see how it cooled into layers all those millennia ago.
