Caves : Exploring Hidden Realms Book

From Greenland's ice grottoes to the "blue holes" of the Yucatan Peninsula and the limestone chambers of America's prime caving country, a select group of bold pioneers are charting our planet's last frontier, a strange subterranean realm of unexplored depths, unexpected wonders, and exotic life forms.

This unique, stunningly illustrated book, a companion volume to the McGillivray Freeman IMAX® theater film, takes readers on a fascinating expedition into the unkown, guiding us to the heart of a glacier, through the twisting passages of Earth's longest underwater caves, and into the caverns that wind beneath Georgia, Alabama, and Tennessee, where brave men and women risk their lives to open up a vast, mysterious underworld that we have barely begun to explore.

An enthralling blend of hard-core adventure and cutting-edge science, Caves leads us into the breathtaking labyrinth that lies far beneath our feet -- and reveals the long-hidden marvels awaiting the adventurous spirits who dare to seek out Earth's deepest secrets.
