The ancient trees had been undisturbed for more than fifty thousand years before finally being uncovered by Hurricane Ivan in 2004. Acclaimed science writer Jennifer Swanson brings readers along with a group of scientists as they work to explore and map the site, collect samples of cypress wood, and learn about the marine creatures that live here--namely, shipworms.
