Geologic Survey Maps (numbers beginning with I 19. These include
Colorado Topographic maps (I 19.81:) and
U.S. Topographic maps I 19.98:).
Bureau of Land Management maps (numbers beginning with I 53.)
NOTE: many maps received before 2007 are not cataloged. See shelf list or ask for assistance.
If you do not find what you need in the catalog, check Prospector, and then Illiad (Interlibrary loan).
