There are two quartz boulders here known as the ‘Rocking Stones’. One is 3x1.8x0.7m and the other 2.5x1.3x0.7m. They are thought to be the remains of a recumbent stone circle. Aubrey Burl suggests that the stones were taken from outcrops half a mile to the SW.
It is possible that there was another circle north of New Deer at NJ 881483, where the Hill of Culsh monument now stands.
