Photographer's Note

We are on Sharpitor, one of 160 tors on Dartmoor.

Click on the picture to open a new tab and a larger version.

Made of granite; Dartmoor granite is about 280 million years old. The processes resulting in the formation of the Dartmoor tors started as the granite cooled and solidified from molten rock at a temperature of 900 - 1000 degrees C. The minerals which make up granite crystallised as closely interlocking grains forming the hard rock.

Tors usually overlie unaltered bedrock and are thought to be formed either by freeze-thaw weathering or by groundwater weathering before exposure.

Masses of broken pieces of granite litter the ground as here, but many appear as rock formations with many cracks and splits dominating the moorland views.

It was a very windy and quite cool morning.
Note the people on the left hand side of the shot, that will give you an idea of the scale.

Thanks for looking.
