When it was built in 1937, Treasure Island was considered to be one of the largest man-made islands in the world. Located in the middle of San Francisco Bay, the 400-acre island was constructed out of dredged bay mud in a remarkable feat of Depression-era civil engineering by the US Army Corps of Engineers. Its alluring name is an allusion to the fabled remnants of the California Gold Rush found in the ocean sediment that formed the island.

This collection of essays tells the story of San Francisco's Treasure Island-an artificial, disconnected island that has paradoxically been central to the city's urban ambitions. Conceived as a site for San Francisco's first airport in an age of automobile and air transport, Treasure Island hosted the Golden Gate International Exposition (GGIE) in 1939 and 1940, celebrating the completion of the Golden Gate and the San Francisco-Oakland Bay Bridges. With particular focus on Asia and Latin America, the GGIE promoted peace, harmony, and commerce in the Pacific. Treasure Island's planned use as an airport was scuttled when World War II abruptly reversed the exposition's message of Pacific unity, and the US government developed Treasure Island and the adjacent Yerba Buena Island into a naval training and transfer station, which processed 4,500,000 military personnel on their way to the Pacific theater.

The book will be of interest to general readers as well as teachers, scholars, and practitioners in the fields of geography, architecture, city planning, urban design, history, environmental studies, American studies, Asian studies, and military history, among others.
