It is not as widely known as it should be that Britain has the most varied geology of any country in the world. This book is a celebration in words & pictures of what its mountains are made from & how they got there. This in turn determines what theyre like to climb scramble on or walk over. Why is Skiddaw slate so slippery? How do tors form? Why is gritstone so difficult? Why is Lakeland so picturesque & the granite lands so grim & forbidding? Geology is destiny whether its the rubbishy nature of gullies & screes the sculpting of valleys by ice or the landslip weirdness of Quiraing on the Isle of Skye. British mountains contain many interesting & different ingredients: gneiss & granite & gabbro; limestone & sandstone; schist & slate; the product & the debris of tectonic shifts volcanoes earthquakes & glaciers over many millennia. This book explains all this to the layman from an expert but personal perspective & will add immeasurably to the fun & satisfaction to be gained from any day in the hills.
