This book provides an overview of the geology of Scotland's East Sutherland and Caithness regions, and includes guides to geological excursions. This area contains many excellent localities that are popular for instructional field courses and recreational visits to view the geology and to collect fossils. The area is also popular with the oil industry as an onshore analogue for several offshore oilfield reservoirs.
