About this collection

The Historical California Topographical Maps collection contains over 700 maps of California quadrangle maps issued by the United States Geological Survey. The maps cover the entire state of California in three sizes -- 15-minute, 30-minute, and 60-minute. Included are multiple editions of the same maps from as early as 1886 and as recent as 1977. The maps were digitized primarily from three physical collections -- the University of Southern California (USC), the University of California at Los Angeles (UCLA), and the Los Angeles Public Library (LAPL). Many of these maps are not in the USGS National Center in Reston, Virginia, as of the time of their digitization (ca.2002).

Thanks to Li Hunt for gathering these maps from their disparate locations in order to make them available here.
