Underwater archaeology holds a special place in historic preservation. Dramatic, risky, cold, and murky are all words that come to mind. But for the stalwart archaeologists of the United States Naval History and Heritage Command it’s not just about finding history. It’s also about protecting the 242 year legacy of the United States Navy. Dr. Robert Neyland, the head of the Navy’s Underwater Archaeology Branch, is leading that effort and has worked on some of the nation’s most famous underwater projects, including the iconic H.L. Hunley in Charleston, South Carolina. Get ready for a deep dive into the world of naval underwater archaeology on this week’s PreserveCast.
