Standing proudly at the junction of Crossflat Farm and Dale Road sits one of Renfrewshire's most intriguing natural landmarks — the Clochoderick Stone.
This impressive glacial erratic measures 12 feet high, 17 feet wide and stretches 22 feet in length. Deposited around 18,000 years ago during the last ice age, the volcanic rock differs from the soil beneath it but matches bedrock found in hills several miles north and west.
According to local legend, druids once used this 'rocking stone' to dispense justice. The accused would stand upon it, and the stone's movement would determine their innocence or guilt.
Another tradition claims the stone marks the burial site of Rydderick Hael, a Strathclyde monarch credited with defeating paganism at Arthuret near Carlisle and converting the region to Christianity.
The Kilbarchan Civic Society erected an explanatory plaque in 1993. You'll find the stone easily enough — it even has its own postcode: PA10 2PF.
