The only British Guide to the geological controls on the D-Day landings in Normandy. The guide puts into context many of the reasons why the Normandy coast was selected for the invasion, reasons for which most people are, or were, unaware. The four itineraries are based on examining the solid (mainly highly fossiliferous Jurassic strata) and superficial (such as Pleistocene loess) geology exposures associated with and adjacent to the main landing areas, Sword, Juno, Gold, Omaha and Utah Beaches, and examines them in terms of water supply, aggregate sources, airfield sites and cross-country movements. The second edition, published in 2024 to help mark the 80th anniversary of the 1944 D-Day, incorporates new historical information and additional illustrations, many in colour, and draws on additional archive material, including contemporary War Diaries of some of the military units involved. An index to place names and glossary are incorporated.
