Engraved in Copper: A video preview

Our current exhibit, Engraved in Copper: The Art of Mapping Minnesota, features 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.

Engraved in Copper is on display through May 22, 2017 at Elmer L. Andersen Library on the west bank of the University of Minnesota campus.
