For over 30 years, hundreds of volunteers have gathered at Mammoth Cave National Park to participate in America's premier cave restoration project. The Mammoth Cave system, the longest cave in the world, has been victim to over a hundred years of tourism, a trade that has taken a toll on the cave. Now, cavers and cave enthusiasts - all volunteers - return to the cave year after year to repair the damage and return sections of the cave back to nature. Follow the author in his account of cave restoration, then follow through muddy crawlways, chilling underground streams, and up dangerous climbs as he explores unknown passages in search of adventures.
