The author has selected twenty-eight caves from around the world and, following three pages of introduction to caves in general, devotes one or more pages to each, with at least one large color photograph. Many of the caves are big: Mammoth Cave as the longest cave, Carlsbad Cavern as the largest tourist cave, San Actun as the longest underwater cave, Kazumura Cave as the longest lava tube, caves of Mulu as the largest cave passages, Krubera as the deepest. But some are small caves notable for other reasons: Sterkfontein Cave for paleontology, Grotte Chauvet for paleolithic art, Villa Luz and and the Waitomo Caves for biology. Caves notable for scenery include Lechuguilla, ice caves of Austria, and Skocjanske Jame.
A few of the photos aren't sharp enough to warrant the size they are printed, and some could have used more skillful preparation for printing. The text appears to have been written for children, because the reader is annoyed by constant repetition of dimensions in both metric and English systems, as well as references back to the introduction whenever terms are used that are even slightly technical. Nevertheless it is informative and explains clearly why each cave qualified as one of the author's choices. If you are interested in caves but don't know where all the caves I mentioned are, you should read this color picture book.--Bill Mixon
