Centered on San Francisco this colorful map presents a huge amount of information in the region from Santa Rosa south to Santa Cruz and east to Livermore. All roads and major streets in cities are shown. The map contains a remarkable array of tones to delineate fifty soil types, each shown with its own color and pattern. But its importance comes from the remarkable detail of cities with buildings, schools, mines, roads, dams, fantastic topographic and watershed information, and much more. The legend uses icons to indicate 25 physical features, topography and more. Surveyed by L.C. Holmes, Department of Agriculture and J.W. Nelson, University of California.
