The Map Collection contains over 1,300 mining maps of Colorado. Most of these are unique—they can be found no other place than in the Arthur Lakes Library. All of the maps are individually cataloged and can be found using the Library Catalog.
Some of the maps are scanned and can be found in our Institutional Repository.
To find a map of a mine in the Library, search the Library's Catalog for the name of the mine.
Most mining maps show a mining district or region. Consequently, it is often necessary to pull many maps of an area and examine each of them in order to find a particular mine. Most of mine maps in our collection show only the location of the claims, not the tunnels. Very few maps show cross-sections of a mine.
