Dirrington Great Law is a hill in Berwickshire. The summit, which is at 1,306 feet above sea level, is around a mile and a half south of Longformacus and five and a half miles west of Duns. It is an isolated hill, to the south of the Lammermuir Hills.
Dirrington Little Law, a mile to the south-west, rises to 1,180 feet.
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, 77 feet, 70 feet, and 28 feet in diameter.[2] The cairns are composed of stones excavated from the hilltop, rather than from loose stone gathered from the ground.[3]
