Jim White saw what looked like smoke coming from ahole inthe ground; he investigated and found the "smoke" to be a stream of bats-millions of bats. He got a rope, let himself down, and found the world's most beautiful and greatest system of caves. A National Geographic Society expedition led by Willis T. Lee was the first to exploreand survey the caverns (page 724).
