Rowley Rag
Rowley Rag was a volcanic dolerite stone quarried in the stone quarries (known locally as the 'Quacks') of the Rowley Hills in the West Midlands of the United Kingdom. The main quarry was on Turner's Hill, and in the 1960s was, in fact, two separate quarries, the Edwin Richards and Hailstone quarries, with a road between them leading to the top of the hill. At that time, hexagonal pillars similar to those of the Giant's Causeway in Ireland could be seen on one of the quarry faces. The Edwin Richards quarry was combined with the Hailstone quarry by removing the disused road between them. It remained active until 2008, operated by Midland Quarry Products. During the 1980s and 1990s, the quarry on Rowley Hill in Rowley Regis was used as a landfill site. There is now a golf driving range on top of this disused quarry and landfill.
