As a special service to the mapping community, MyTopo is proud to host this collection
of historic USGS topographic maps. This ongoing project is headed by historian
Christopher Marshall and compiled through the efforts of many individuals.
We are honored to be the stewards of this fine collection, making it available to
all via the World Wide Web.
For a discussion on the evolution of USGS maps, please check out the section on
"Historic Topographic Maps". Select "About the Collection" for information on
how you can help expand this library. Maps are scanned and processed by
volunteers who share an interest in historic maps. MyTopo sponsors their
efforts by providing free web space for this collection.

Navigator mapping software, please visit MyTopo.com.
