Caves of Fire - 2nd Edition

Author Dave Bunnell has made an extensive revision to his full-color First Edition, Caves of Fire:

Inside America's Lava Tubes, published by the NSS in 2008. Twenty new pages have been added and many revisions have been made to the existing pages, including many new photos taken by the author and his friends. The 144-page Second Edition has expanded coverage of lava tube genesis, including spectacular new images which peek into active tubes to reveal lava formations in the making.

The book has two purposes: first, to highlight the many bizarre forms that can be found in lava tubes and explain how they came to be, using the most photogenic examples the author knows of; and second, to present descriptions and images from dozens of lava tubes open to the general public on state, federal, or private lands for those who want to enjoy exploring lava tubes for themselves.
