Sunken City

This guide to Sunken City in San Pedro opens on a clifftop neighborhood built in the 1920s by developer George Peck, and the second of January 1929, when a water pipe burst under a hotel here for no obvious reason. You'll hear how a Caltech geologist read the cracking streets that followed, and how families raced to haul their houses off the moving ground before it was too late. It follows the slide through the decades after, as the bluff kept shifting beneath the old streetcar line.
