1792 Historical South Dakota Counties Map

Why would you want to see historical Google Maps? County boundaries in the U.S. have changed over 17,600 times since America was settled in colonial times! This historical counties tool built on Google Maps will help you make sure you’re searching in the correct county for the place and any historical date you are researching.

Research with confidence knowing that this tool is built using the complete dataset of the authoritative Newberry Library’s Atlas of Historical County Boundaries project.

Quick Tips for using this 1792 Historical South Dakota Counties Map tool

  1. There are four ways to get started using this Historical U.S. Counties map tool
    • Type any PRESENT-day place or address in the “Search places” box above the map and choose the one you want from the auto-complete list
    • Click the map to see the historical county name for where you clicked (Monthly Contributors also get Dynamic Maps)
    • To search using GPS coordinates use the “Find lat long” box in the top right above the map*
    • Click the button in the upper right corner of the map to use your current location. Click the button again to automatically update your location every 1, 5 or 10 minutes (Monthly Contributors also get an option to update every several seconds, shown as ◉A for Active).**
    Then, type any HISTORIC date or year in the “As of date” box and click GO! The date can be a 4-digit year or a specific date. Dates can be formatted as YYYY, M/D/YYYY, M-D-YYYY or YYYYMMDD.
    Historical county boundaries will draw, and the historical county name for the location will appear above the map. Click the “more…” button for details on the latest boundary change that occured prior to the date you specified, including reference to the particular statute that triggered the change. The latitude and longitude for the blue dot is also displayed.
  2. Optionally, check the “Show labels” checkbox in the lower left corner of the map to see the names of the historical counties on the map
  3. Check the “Show chronology” checkbox in the lower left corner of the map to see a complete listing of every county boundary change for your chosen location from the date you typed back in time to original county formation
  4. NEW! Use the SHOW PRESENT DAY LAYERS panel in the lower left corner of the map to show present-day county lines, city limits, civil townships and section township range with the historical counties. If you have historical county labels checked and are also showing present-day civil townships, then civil township labels will also draw.
  5. NEW! Use the “Find parcel” tool below the map to search for a known Section, Township and Range, for example from a land deed. Tip: You don’t have to specify a Section if you only know the Township and Range. Also, you can leave the PM (Prime Meridian) set to “any” and the tool will let you know if there are multiple matches. NOTE: THIS SEARCHES PRESENT-DAY TOWNSHIP RANGE, NOT HISTORICAL TOWNSHIP RANGE.

FAQs for 1792 Historical South Dakota Counties Map

How do I view a map of 1792 Historical South Dakota Counties on Google Maps?
View this 1792 Historical South Dakota Counties map tool. The historical South Dakota counties will be displayed on the map, and you can also overlay present day counties, townships and more.

Why was this tool created? Many people have requested to be able to see historical county lines from the Newberry Library’s Atlas of Historical County Boundaries displayed on top of Google Maps.

While some other tools can show the Newberry Atlas in GIS formats for Google Earth, requiring downloads and installation, this free tool shows the entire Newberry Atlas of Historical County Boundaries overlaid on Google Maps in a web browser. Therefore, you don’t have to download, install or import anything, and you can even use it on your smart phone or tablet.

Coverage Notes

– Coverage includes all 50 US states, from as early as 3/4/1629 through 12/31/2000. For present-day county lines use the County Lines on Google Maps tool.

Other Notes

  • The Search places box uses a standard Google Maps geocoding engine, therefore you can type PRESENT-day street addresses, road names, points of interest, etc. to see what historical county that present-day location was part of as of the historical date you specified
  • You can use the < and > buttons on the sides of the ‘As of date’ box to quickly jump back and forward a decade.
  • For convenience, when you specify only a four-digit year (and not a full date), the tool will default to using the US Federal Census date that was used in that decade. (This is also true when using the < and > buttons.) Lining up with Census dates makes genealogy research easier when comparing to other records. If you do not want to use the Census date, specify an exact date instead in M/D/YYYY format.
  • Some counties or regions were claimed by more than one jurisdiction in some historic years. When this is the case, more than one county will be listed, and the ‘more…’ button will show you the details of the jurisdictional claims.
  • The map layers from which this information is extracted are very large, so it may take several seconds to finish drawing
  • Note that typing an address will zoom in the map very close, whereas typing a city or county by itself will show you a map with a wider view
