Geographic features that appear on topographic maps in the United States are listed in an online database maintained by the federal government’s United States Geological Survey and the U. S. Board on Geographic Names.
This entity is usually referred to as USGS. The database is called the Geographic Names Information System, or GNIS. Many genealogists use it frequently to find places, identify the county location, and determine the coordinates.
The following table contains all topographic features in the GNIS identified as airports, fire departments, towers, tunnels, mines, and parks within Grainger County. Places that no longer exist are identified with “(historical).”
The table also includes the latitude and longitude and name of the 7.5′ USGS topographical quadrangle map on which the place is shown.
Please note that this is not a comprehensive list of all miscellaneous topographic features in the county. It is simply the government’s mapping system’s list. Click here to search GNIS for other topographical features or locations.
