One of the driving motivations of U.S. settlement of the Rocky Mountains was mining. Beginning in the late 1850s, valuable minerals attracted fortune seekers to Colorado. As government organizations helped settle the lawlessness of mining districts, it was necessary to accurately map who had rights to plots of land. Maps painted a picture of mining’s booms and busts, noted prospectors’ names, and showed the development of Colorado’s famous mountain towns. Some of the original maps are works of art. This talk will illustrate Colorado’s historical mining maps using the rich collection of the Arthur Lakes Library.

Christopher J.J. Thiry has been the Map & GIS Librarian at the CO School of Mines Arthur Lakes Library since 1995. He holds a BA in history and an MLIS from the University of Michigan. He has taught numerous workshops in map librarianship, GIS, map resources, and map cataloging.
