Introduction
South-east Scotland displays much of the country’s scenic variety in one small region. The distinctive volcanic hills rising out of the glaciated East Lothian plain; the spectacular cliffs of the Berwickshire coast; the rounded Lammermuirs, made of rocks from the floor of a long disappeared ocean; the long narrow valleys of the Tweed and its tributaries and the gently rolling lowlands of the Merse to the rugged granite hills of the Cheviot along the English border are all part of that diversity. This booklet explains how this varied landscape was fashioned over 500 million years of geological time.
