By investigation of soils and erosional features, we can extend Edinburghs history back to the end of the ice-ages, and the movements of glaciers across the region can also be discerned.

However, before the ice-ages, we are confronted with a vast time gap of around 300 million years. It is when we investigate the bed-rocks that it is possible to take the story back further, which is the purpose of this book, now available in paperback. Edinburghs rocks, formed between 300 and 450 million years ago, afford startling perspectives of the extraordinarily different environments of those remote times.

The sandstones with which much of the city is built, were washed down in rivers meandering through a tropical landscape. Coals from the seams of the Midlothian coal-field are fossil relicts of extensive rain-forests that thrived in steamy coastal swamps. The more visible rocks, such as the famous Castle Rock, are memorials to volcanoes that erupted about 340 million years ago. Older than these, and dating back to more than 400 million years, are the Braid, Blackford, and much of the Pentland Hills, while the oldest rocks within a 25 mile radius of Waverley Bridge are tucked away in a few small patches of the Pentland hills.** Beautifully produced, lovely to hold and read...an excellent book for all geologists.
