Engraved in Copper

Engraved in Copper: The Art of Mapping Minnesota opened this week at the University of Minnesota’s Elmer L. Andersen Library. “This exhibit highlights unique engraved copper plates used to print topographic maps of Minnesota in the early 1900s, surveying and mapmaking techniques, and government documents related to the process. The plates are part of the evolution of government mapping and the history of the United States Geological Survey, from early mapping efforts to Geographic Information Systems.” Runs until 22 May.
