This Hutton Bicentenary (1996) edition of Lothian Geology describes the geological origins of some of the most famous landmarks in Central Scotland. These include the remnants of the c. 350 million year old volcano which forms the distinctive hill and crags of Arthur's Seat which dominates the Edinburgh skyline. The 20 excursions also visit a wide range of sedimentary and volcanic igneous rocks exposed in incised valleys, along the coast and highland areas of the Lothian district.
