See how the San Francisco Bay Area has developed over the last century.

From the Scout Report:

The University of California Berkeley's Earth Science's and Map Library has produced a Website that highlights historical maps of the San Francisco Bay area from 1895 to the present. The maps, produced by the US Geological Survey, are scanned topographic 7.5 and 15-minute quadrangles and can be zoomed to impressively fine detail. The site allows visitors to choose from the quadrangle index, search by place name, or browse by clicking on the general overview map. Researchers in cartography, general history, or the San Francisco Bay area should find this site enjoyable and informative.
