The Dhustone Section. Ink and water-colour drawing in the Shropshire County Museum Service geological collections at Ludlow. This meticulously contructed geological section illustrates the rocks and strata of England, from the most ancient (at the base) to the most recent (at the top), as they were understood in mid-Victorian times. The prominent feature, coloured in red, is thought to represent teh famous Shropshire dhustone, an illustrative igneous rock. For centuries, this hard black dolerite has been quarried for roadstone on Titterstone Clee Hill, five miles east of Ludlow. Photograph by Gareth Thomas FRPS.
