Geologically, the two Dirrington Laws comprise Carboniferous volcanic felsite (riebeckite), and may be the remains of a laccolith, a type of volcanic intrusion into the surrounding sedimentary rocks of the Old Red Sandstone.[1]
At the summit of Dirrington Great Law are three large circular cairns, 23.5 metres (77 ft), 21 metres (69 ft), and 8.5 metres (28 ft) in diameter.[2] The cairns are composed of stones excavated from the hilltop, rather than from loose stone gathered from the ground.[3]
