Ironbridge Gorge

The Ironbridge Gorge is a deep gorge, containing the River Severn in Shropshire, England. It was first formed by a glacial overflow from the long drained away Lake Lapworth, at the end of the last ice age. The deep exposure of the rocks cut through by the gorge exposed commercial deposits of coal, iron ore, limestone and fireclay, which enabled the rapid economic development of the area during the early Industrial Revolution.
