Take geology in your hands and read the colourful descriptions of the fascinating walks available in this area. Many of them are circular, varying in length (half day or full day) and aimed at ramblers interested in the origin of their surroundings as well as Derbyshire's incomparable scenery. A brief introduction to geology will help the interested walker appreciate fully that what they see along the way are not simply 'rocks' but materials that conceal fascinating facts relating specifically to this part of the earth's crust - its minerals and fossils. Detailed maps are included plus information about parking facilities, and the all-important venues for refreshments along the way. The comprehensive glossary of terms, which covers the identification of Peak District Rocks, forms an invaluable supplement providing 'at a glance' information for the reader.
