This is a painting I did a few years ago of a friend standing beside one of the outcrops at the top of a hill in the Dartmoor national park.
The rocks have been weathered over the millennia to create flat plate like structures stacked up on top of each other. Sometimes the base will be of softer rock and so the stack will be formed above a narrow neck of rock where the surrounding stone had been worn away. Another place to find these sort of outcrops is in Yorkshire. You can also get limestone pavements where the rock is at ground level but there are large cracks going down deep between the rocks with plants growing up, taking shelter between the stones. These can be found up at Malham cove in Yorkshire.
My friend used to fly gliders over Dartmoor, so he knew his way around the area. It is a beautiful part of the world, high up above the surrounding countryside with rolling hills and wide skies. Sometimes it snows up there and it can be very bleak in the winter . I can imagine trying to shelter behind these rock on a cold winters day with an northerly wind blowing snow and sleet at you. I guess Dartmoor ponies might even have sheltered there.
The painting was quite small and was painted with acrylic on canvas. It went to a good home.
