Once you've gathered as many facts about family history and customs as possible, turn to maps to uncover more specific information or to solve historical mysteries.
In the United States, birth, death, property, and some other kinds of records are normally kept by county governments. If you can name the place where an ancestor lived, new or old maps of that place might show the county seat where useful data about your relatives can be obtained.
Many towns, counties, cities, and even countries have experienced numerous name changes over the years. Historical USGS maps can help locate places that have had name changes or have disappeared. You can also use the Geographic Names Information System to search for place names that might no longer appear on newer maps.

How do I find, download, or order topographic maps?
The U.S. Geological Survey (USGS) has been the primary civilian mapping agency of the United States since 1879. USGS topographic maps have been published at many scales, but 1:24,000 (also referred to as a 7.5-minute quadrangle) has been the standard topographic map scale since 1947. For Alaska the standard scale is 1:25,000. All dates and all scales of our topographic maps can be freely...
Where can I find indexes of USGS topographic maps?
View map indexes on these interactive maps (you must zoom in to see the index lines and map names): Map Locator on the USGS Store - Click the icon on the left that looks like two pieces of paper and select “1:24,000” for our standard map series. TopoView - Click on any of the round map scale indicators on the right side of the map. The National Map Viewer - Click on the Layer List icon at the top...
What is the Geographic Names Information System (GNIS)?
The Geographic Names Information System (GNIS) was developed by the U.S.Geological Survey (USGS) in cooperation with the U.S. Board on Geographic Names (BGN), which maintains cooperative working relationships with state names authorities to standardize geographic names. GNIS contains information about the official names for places, features, and areas in the 50 states, the District of Columbia...
How can I name an unnamed natural feature?
Proposals to name an unnamed natural feature can be submitted to the U.S. Board on Geographic Names (BGN). The BGN is responsible by law for standardizing geographic names throughout the Federal Government, and promulgates policies governing issues such as commemorative naming, derogatory names, and names in wilderness areas. Please note that no natural feature (and certain manmade features) can...
Does the Geographic Names Information System database contain entries for obsolete names and geographic features that no longer exist?
Yes, The Geographic Names Information System (GNIS) actively seeks names of features that no longer exist. The term "historical" as used in the GNIS specifically means that the feature no longer exists on the landscape. An abandoned ghost town, for example, still exists so it is not historical. Historical features have no reference to age, size, condition, extent of habitation, type of use, or any...
How can I find USGS historical photographs?
The USGS Photographic Library, located at our library in Denver, Colorado, is an archive of still photographs dating from the 1870s and taken by USGS scientists as part of their field studies. The works of pioneer photographers W.H. Jackson, T.H. O’Sullivan, Carleton Watkins, J.K. Hillers, Thomas Moran, A.J. Russell, E.O. Beaman, and William Bell are represented in the collection. Topics include...
Why are some of the historical topographic maps yellowed and why do some have extra stamps or marks?
The goals of the Historical Topographic Map Collection (HTMC) project are to find, catalog, and georeference all USGS topographic quadrangle maps published prior to 2007. The overall purpose is to preserve the map archive for scientists, historians, and the public. Library copies of maps (many of which have library stamps) were therefore scanned "as is". Map restoration is not part of the current...
Where can I find historical photographs from the Great Surveys of the American West?
A number of images from the "Great Surveys of the American West" can be downloaded through the online USGS Photographic Library. Before the USGS was established by Congress as a part of the Department of Interior, four surveys of the western United States took place between 1867 and 1879. Surveys led by Ferdinand Hayden and John Wesley Powell were sponsored by the Interior Department, and Surveys...
There are multiple copies of the same map in your Historical Topographic Map Collection that all have the same date. Is there a difference between those maps?
Two or more historical topographic maps with the same date typically result from revisions and reprints. The differences are often minor. The date used to identify a map is in the lower right corner. If there are multiple editions with the same compilation date, look for additional dates in the lower right portion of the map collar that might differentiate them: Date on Map -- The year of base...
How do US Topo maps differ from historical USGS topographic maps?
Historically, USGS topographic maps were made using data from primary sources including direct field observations. Those maps were compiled, drawn, and edited by hand. By today's standards, those traditional methods are very expensive and time-consuming, and the USGS no longer has funding to make maps that way. A new USGS topographic map series was launched in 2009 and branded "US Topo." Though...
