"Geological Map of the San Francisco Peninsula", U.S. Geological Survey (USGS)

This is an amazing, near photo-realistic map that resembles today's satellite images. It was drawn by Andrew C. Lawson who used shadowing to enhance the photographic quality of this remarkable map. It includes all of the San Francisco peninsula from the Golden Gate south to below San Mateo to Belmont and Seal Cove. It is a printed color gravure by Julius Bien of New York. The map was published by the U.S. Geological Survey, Fifteenth Annual Report as "Plate V" in the section "Sketch of the Geology of the San Francisco Peninsula by Andrew C. Lawson."
