The Map Collection contains over 1,000 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.
Unfortunately, we have very few maps of specific mines. 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.
