It seems you can hardly drive along a road through Dartmoor without passing by a stone circle or ten: the local OS map is positively littered with them. But whenever we get close enough to spot one from the road, we have to stop and take a closer look.
The circle, which we later found is known as Soussons cairn, is a Bronze Age burial site with a tomb at the centre, surrounded by a number of standing stones. Centuries of wind and rain have worn down the rocks into odd shapes, and the effect somehow puts me in mind of a mouth full of jagged teeth. Nevertheless, I always find stone circles to be a relaxing spot for a break and to take in the scenery.
