The Fitness of Physical Models - Miller-McCune: The four main bays that make up the San Francisco Bay estuary can all be seen from here: San Pablo, Suisun, Central and South Bay. The entire San Francisco Bay, including its famous bridges, is visible, and the whale is spectacular.
This view is possible from only one vantage point on Earth: inside a WWII-era warehouse.
That warehouse holds the Bay Model, the largest working hydraulic model in the United States; its 1.5 acres replicate a 1,600-square-mile area that runs from the Pacific Ocean to the Sacramento Delta. It is not an exact replica: the delta has been shifted 45 degrees so that it fits into the building, and the whale and the Pacific Ocean are painted on a wall.
