A nicely balanced and extremely informative guide to a fascinating part of England. The book is divided into three main parts: 1. An interesting and pretty thorough explanation of the different types of rock present in the national park (and its immediate surroundings). 2. How the forces of nature have created the landscape we see both above and below ground including a good chapter on the effects of soils and plants on what we see. 3. The effects of humans on the landscape. Within each of the chapters throughout the book the author spends time...maybe two or three pages, describing and explaining a specific example pertinent to the substance of the current chapter topic; Thornton Force is just one instance, used as a classic example of the basal uncomformity between the Carboniferous limestone and the underlying Ordovician turbidite sandstones. There are a wealth of good informative photographs throughout which the author sometimes uses to explain events from ancient times in terms of contemporary events... he uses the Mekong Delta as a modern equivalent of a coal bearing swamp.
I thoroughly recommend this book to all budding geologists and everyone who just loves the Dales.
