"Crystal Giants in the Caves of Naica." Edited by Giovanni Badino. La Venta—Explorazioni Geografiche, Italy; 2008. ISBN 978-88-95370-04-0. 8.5 by 8.5 inches, 48 pages, hardbound. About $23 from cave-book sellers or the Association for Mexican Cave Studies at amcs-pubs.org. [AMCS price $20 plus shipping.] Most cavers who are reading this will have, unless they recently immigrated from Mars, heard of the Cave of the Crystals in the Peñoles Mine in the town of Naica, Chihuahua, Mexico. There have been numerous articles and web pages about the 10-meter-long gypsum crystals in the cave room accidentally opened by mining in 2000, but this is the first book publication about them. The main feature of the book is eighteen large color photos, some covering two full pages, but there is also text, translated from Italian, about the discovery of the room, the techniques developed to explore and map a cave that has 100-percent humidity and a temperature of 118 degrees F., and the future of the cave. The room is only accessible because sixteen thousand gallons of hot water per minute are being pumped out to keep the mine dewatered, at a cost of a million dollars a month for electricity. A mineral vein is sort of like a cave--you can't tell where the ore will end until it does. When it does, photos like those in this book will be all that remains for us of the Cave of the Crystals.—Bill Mixon
