High on the plateau (350m) some 32 small stones survive, some barely showing above the heather, 10 of them still upright, and none more than 60cm high. They form an egg-shaped setting nearly 46m by 43m, most of the stones lying on a 41.5m true circle (50 megalithic yards) but the western segment formed on the arc of a separate notional circle 25.6m or 31 my in diameter whose circumference passed through the centre of the larger circle. The perimeter of the setting was determined by straight lines joining the outer arcs of the overlapping circles. This, at least, would be the theory suggested in recent years-that our ancestors had devised careful mathematical formulae linking an apparently standard unit oflength, the 'megalithic yard', to basic geometrical shapes (cf Burgh Hill no. 100).
