Topos in the Library
The Map Collection contains a large number of topographic (topo) maps including an extensive collection of historic maps of Colorado.
USA:
The Library has complete sets of topographic maps produced by the US Geological Survey (USGS) at a scale of 1:24,000 (the most detailed maps available for complete coverage, and often called "quadrangles" or "7.5 minute sheets") of the following states: Colorado, Arizona, New Mexico, Utah, Wyoming. These topos are segregated to one side of the Map Collection and are filed first by state, then by name of sheets. Indexes to these maps can be found in the green booklets on top of the topo map cases. The Library has topographic, although not complete, coverage of the above listed states at scales of 1:31,680, 1:62,500, 1:125,000, and 1:250,000. The Library has complete sets of topographic maps of the entire United States produced by the USGS at a scale of 1:100,000, and 1:250,000.
WORLD:
We strive to have complete topographic coverage of South America, Africa, and parts of Asia. Accordingly, the Library has good coverage at 1:500,000, some coverage at 1:250,000, and spotty coverage at 1:50,000. The Library has created interactive indexes to world topographic maps.

Additional indexes to all the world topographic sheets have been created and placed in binders on top of the map cases. The indexes are ordered by continent, then by country.
