During the Ice Age boulders were brought from the Arenig Mountains (several miles west of Lake Bala) of North Wales. These boulders, of volcanic origin, may be seen in Cotteridge Park; in Bournville Lane; near the entrance to Bournville Station; on the hill of Frankley Beeches and near Northfield Church is The Great Stone. About forty of these erratic glacial stones have been found in this district and a very large one was recently unearthed during the excavations at the Row Heath Recreation Ground, adjoining Bpurnville Village. The boulders (of felspathic ashes, and felsites) may be traced from the Lickeys in a north-westerly direction through the Tattenhall and Seisdon districts to Ruabon, the Vale of Llangollen, and so to the Arenig Mountains. Thousands of tons of debris frozen in the ice were carried by the glacier and deposited in various localities as the ice melted. The clay, used for brick-making, found in thick beds, as at California, between Harborne and Northfield, was thus brought.
