The characteristic landscape of the Lake District is influenced by its geology. The huge array of different rocks found there determines the shape and appearance of the fells and dales. Also, as the dominant building material in the region, rocks impact both the local architecture and the economy through quarrying. A simple easy-to-read guide to the rocks of the English Lake District, with nearly 200 colour illustrations including diagrams, maps and photographs, this book provides an understanding of the main types of rock and characterizes over sixty of the most common rocks. It describes where to find them and how to recognise them in the landscape. Details are given of the use of rocks in local buildings and how the rocks are still quarried today, and finally, their importance to the local economy.
