MapFinder™ is a free application that shows the 7.5 minute quad (1:24,000 USGS United States topographic map) boundaries for the lower 48 states and Hawaii. The user has the ability to search by section, township, and range, County and State, or by 7.5 minute quad name. Each boundary has an identification point that gives you information about the USGS topo map. This information includes the map name, scale, and year. The most exciting feature of this application is that there is a download link that enables you to download the topographic map for free!
Note: MapFinder™ does not work in the 64 bit version of Windows Internet Explorer.
