David Sanger and John Hart's classic book San Francisco Bay: Portrait of an Estuary was released in October 2003.

A portrait of San Francisco Bay, the largest estuary system on the west coast of the Americas, this large-format photography book showcases a fragile yet essential centerpiece of life in the Bay Area.

Sponsored by the National Audubon Society and The Bay Institute,San Francisco Bay: Portrait of an Estuary is published by the University of California Press and designed by award-winning designer Jennifer Barry

"The bay is brought beautifully to life through Sanger's eye for the spectacular vista and the unusual angle, as well as his passionate understanding of the details that make up the whole."

George Olson, Director of Photography, Sunset magazine

"This impressive collaboration between an environmental historian and a nature photographer is a celebration of the San Francisco Bay's natural beauty and environmental value. As a life-long San Franciscan who has a deep admiration for the Bay, I believe residents and visitors alike will enjoy this wonderful introduction to the Bay and will be moved to cherish and protect this California treasure."
