The US Army Corps of Engineers used to use this hydraulic scale model of the San Francisco Bay and California Delta to study the hydrology of the area. It was instrumental in proving that the Reber Plan, an attempt to fill in the bay with land reclamation, was a bad idea. Now after computer models have supplanted analog models, it is open to the public as a museum. Also contains an exhibit on Marin shipyards during the Pacific War.
Hands-on children's museum with lots of environments to play in. Perhaps locally most beloved for the Bay Hall, a play area themed after the San Francisco Bay, including a pretend fishing boat and toy shipping containers that you can load on toy boats with toy cranes.
