From deserts to beaches to subterranean tunnels, the Lost LA video series explores Southern California's past with the help of primary source material from the archives of the University of Southern California Libraries. Episodes explore beloved landmarks like Dodger Stadium and Yosemite ("Before the Dodgers" and "Yosemite"), subcultures from surfers to radio evangelists ("Beach Culture" and "Ghost Towns"), and untold stories such as Los Angeles's geographic segregation ("Coded Geographies"). Each 20-30 minute episode is hosted by writer and public historian Nathan Masters. Some of the 23 episodes are accompanied by lesson plans, which can be found by clicking "Lost LA Curriculum Project" in the "Overview" section on the page linked above. Readers can also click "Articles" for text-based articles on topics not covered in the video series, such as deeper dives into various Los Angeles neighborhoods and features on the 1932 and 1984 Olympic Games. Lost LA is produced by KCET, part of the Public Media Group of Southern California, with funding from California Humanities, California State Library, Union Bank, and The Ralph M. Parsons Foundation.
