carnstabba_stone_head. this two piece balancing stone must be by far the largest of the very large grounders on this hill. It is understood that grounders such as these have been deposited here during the ice age and are still in-perceptively on a very slow journey down the slope of the hill. it marks the site of a watering hole some three or four metres away and can be seen from a good distance away. the stone head has the appearance of a reptiles head and is cup marked. from instagram:
