San Francisco Bay, in 1915 and 2008

Source of historic map: San Francisco History Index, by Z Publishing.

Some landmarks of note: Treasure Island, which does not exist in the 1915 map, is an artificial island originally used as an airport and built from landfill that was dredged from the bottom of the Bay during the Great Depression.

The Port of Oakland was also constructed from landfill on the northern side of San Antonio Creek. Some landfilling work is already evident in the 1915 map. The airstrip on the south side of the Creek in the 2008 view is the Alameda Naval Air Station.

To view the entire map overlay in Google Earth or Google Maps, I've posted this overlay as a KML file on the Google Earth Community.
