An In-Depth Look at the History of San Francisco's Estuary

America's largest Pacific Coast estuary, the tidal mouth of a river, is right here in San Francisco. We explore its adventurous history -- from gold miners to Jack London's time stealing oysters -- but also take a critical look at how planting Atlantic oysters and hydraulic mining for gold scarred our natural habitat. Associate professor of history Matthew Morse Booker joins us to talk about his new book, "Down by the Bay," and the future of the estuary.
