Marine archaeologist Jim Delgado uncovers the shipwrecks, secrets, and human stories buried under San Francisco’s streets and waves.

From Gold Rush vessels entombed beneath the Financial District to wrecks off the Marin Headlands, Jim reveals how these “unread books” preserve a hidden record of the city’s boom-and-bust beginnings.​

Along the way, we visit the buried Gold Rush ship Niantic, trace forgotten hulls under downtown sidewalks, meet tragedy under the Golden Gate Bridge, and hear Jim's riveting tale of solving one of the greatest mysteries in U.S. naval history. He shares the poignant human stories preserved in mud: cigar boxes, bunk beds, family photographs, and the long-awaited answers for descendants of sailors who never came home.​
