This is a searchable directory to the entire collection of United States Geological Survey (USGS) Topographic Maps including the 1:250,000 scale maps to the more detailed 1:24,000 scale maps.   These are scans of the original topo maps with collars left in tact. The collars may be useful for identifying reprints and other details.  Whereas, the topo maps displayed in the searchable and precise geo-locatable web application are collarless and is limited to the 1:24,000 through 1:62,500 scaled maps.

You can search for a topographic map by entering the Quadrangle Name for example "Fort McDowell".  If you do not know the name of the map use the drop down menus for the state and county.  By clicking on the squares it will pull up all of the Quad Maps for that location.  You can also narrow the search by year and scale.
