I remember reading and enjoying this book when the first edition came out many years ago. I am also a keen hillwalker and have stood on top of many of the Scottish mountains referred to in the text. In fact, I particularly enjoyed climbing Ben More on the island of Mull, which I remember reading was the last volcano in northwest Europe.

The Scottish Borders region is famed for their frontier history, and attendant myths and ballads. This book is concerned with their more ancient geological history, which is revealed by its rocks. These indicate that the area was once on the edge of a huge ocean – the Iapetus – which met its end between the inexorable crush of tectonic plates.
