"Great Caves of the World is an introduction to some of the most magnificent cave systems in the world. Geologist and caving expert Tony Waltham provides an introduction to the subject before exploring the characteristics of each of the 28 selecte caves. He describes how each one was formed, its environment and location, and how it contributes to our understanding of the underground." "This illustrated book takes readers on a journey to a surprising array of environments, from huge underground rivers and long lava formations to secret temples and ancient archaeological sites. Dwell in forests of sparkling ice colums deep inside the Pinega Caves, Russia; be dazzled by the mineral deposits in Lechugilla Cave, USA, and discover the classic Yorkshire pothole at Gaping Gill, England."--BOOK JACKET.
