Need to print at a "standard" scale (1:24,000, 1:100,000, etc)? Try the deprecated and archived version of this map service:

- Will zoom to same current extent and closest scale.
- You will need to setup the map to same layers, etc.
- ESRI baselayers are not available on the archive version.
NOTE: "pull" on the right side of the pane to resize.
What is this? This tool allows you to search the Kentucky Geological Survey database for geologic descriptions from KGS publications, maps, and field notes and highlight those units on the map.

Many of these descriptions were derived from the more than 700 geologic quadrangle maps that cover the entire state of Kentucky. The "hits" which correlate to the 24K Geologic Formations (see the "Layers" tab to turn these on) are highlighted on the map. Queries run at "zoomed out" scales (1:500,000 and smaller), will display a point for the location (this is the center point of the 1:24K formation polygon). When zoomed in to large scales, the polygon outline will be highlighted. A link to the full report from your search parameters is also given (which may yield results from other reports as well).

To get started, zoom into an area of interest, enter your favorite geologic term ("oolite" or "fissile"?) into the Search Term field, and hit the SEARCH button below...

Some tips:
  • Broad search terms at large extents (e.g. statewide) can yield very large results, and will dramatically slow down this tool and you may get script errors. To alleviate this, use specific terms and search limits (you can limit by geologic age and even specific stratigraphic units) and/or zoom to an area of interest.
  • When zoomed out to scales smaller than 1:500,000 (larger areas), results are shown as points on the map. To highlight the formation polygons, zoom in and rerun the query.
  • Set off compound terms (e.g. "oolitic limestone") with quotes, and separate multiple terms with quotes for each term.
This tool is still in the development stage. We are working on improving the results speed, and adding other features which can be queried (wells and other geologic features).
Search Term(s):
Search limits:
Limit results to the current viewed area (HIGHLY RECOMMENDED**)
**for best results, zoom into an area of interest and query, or use very specific terms and search limits
 only search PRIMARY LITHOLOGY descriptions
Limit by Geologic Age (more info):

    Updates to the Geologic Map Service (5/24/2018)
      New topographic basemap: KY Topographic Map Series (turn this on at the top of the layers under "Base Layers"). This basemap will be turned on by default (with the gray ESRI basemap turned on for areas outside KY - this basemap can be changed in the ESRI basemap gallery).

      This is a newly developed topographic base by the Kentucky Division of Geographic Information which was created by utilizing high resolution topography and imagery data from the Kentucky Aerial Photography and Elevation Program (KYAPED) along with the latest basemap data from KY agencies (KY Transportation Cabinet, KY Division of Water, etc.).

      Read more about this product here: KYTOPO: KENTUCKY’S NEW TOPOGRAPHIC MAP SERIES. This is a fantastic basemap for Kentucky and will have the latest topographic information for the Commonwealth. You can also explore this topographic map series on this ArcGIS Online viewer. The USGS topographic map is still available as a basemap (with or without the 10m hillshade effect).
    We welcome your feedback at:

    Updates to the Geologic Map Service (12/18/2017)
      Added LiDAR-derived sinkholes for Boyle, Bullitt, Fayette, Jefferson, Jessamine, Oldham, and Woodford counties.
    Updates to the Geologic Map Service (12/11/2017)
      Fixed issues with the water wells and springs that were not displaying at the state-wide scale level.

      Symbolize water wells at the state-wide scale level by primary use. See water well legend for primary use types.

      Symbolize springs at the zoomed-in level by spring type. See springs legend for types when zoomed in.
    Updates to the Geologic Map Service (2/9/2017)
      Added coal and non-coal economic points to the layer list. These locations were digitized from the original 1:24,000 Geologic Quadrangles as a part of the KGS DVGQ program.

      Coal mineral points are displayed by mining type. Non coal ore and bulk mineral points are displayed both by commodity and mine type (can be toggled on and off)

    1. Coal DVGQ Locations: layer is located under the "coal" header. Locations where coal was mined, quarried, or prospected as identified on the Geologic Quadrangle maps.
    2. Non-Coal Ore Mineral Points: layer is located under the "economic" header. Locations where ore minerals were mined, quarried, or prospected as identified on the Geologic Quadrangle maps (barite, flourite, flourspar, calcite, etc...).
    3. Bulk Mineral Points: layer is located under the "economic" header. Locations where bulk minerals and geologic materials were mined, quarried, or prospected as identified on the Geologic Quadrangle maps (limestone, sand and gravel, clay, etc...)
      Also added a new "Quick Map Layout" bookmark named "Economic Non-Coal Map" for a quick display of non-coal economic points and areas (quarries). Faults are also turned on with this bookmark.
    Updates to the Geologic Map Service (12/5/2016)
      Added several new methods for visualizing oil and gas wells:
      When the oil and gas layer is turned on (check the box under the "Data Layers" in the "Layers" tab), there are now selections for:
    1. Total Depth Formation: symbolizes and labels the wells by total depth formation. Wells are symbolized green to yellow to red = youngest to oldest.
    2. Deepest Pay Formation: symbolizes and labels the wells by deepest pay formation. Wells are symbolized green to yellow to red = youngest to oldest.
    3. Total Depth: symbolizes and labels the wells by total depth. Wells are symbolized green to yellow to red = shallow to deep.
    Updates to the Geologic Map Service (4/7/2016)
      You can now dismiss this dialog until the next update! Check the box above and hit close button below.
    Updates to the Geologic Map Service (4/16/2015)
      Just added - download functionality for the "Photo & Images" layer. Activate the tool to draw a polygon on the map around desired points, and download into a shapefile or geodatabase. Layer includes a field containing the photo URL.
    Updates to the Geologic Map Service (10/18/13)
    1. Major Update! Map service now uses the ESRI basemap layers and has all the ESRI basemaps available for use. This has several implications:
      1. A new layer selection has been added called "Change World Base Layer (ESRI)" to the basemap layer list. Select the basemap you would like to use from the list of thumbnails. The default is the Topographic base. These are worldwide base layers projected in WGS 84.
      2. The map service projection is now WGS 84 (WKID = 102100).
      3. The map service should be faster and more stable.
      4. The KY Topography and KY Imagery layers can still be turned on. These base layers provide detail that the ESRI basemaps do not provide. These are available in the layer list and overlay on top of the ESRI base layers.
      5. Due to the caching scheme for the ESRI basemaps, the scale levels for the map are different than before. If you need a "standard" map scale of, say, 1:24,000 or 1:100,000 you can use the archived and deprecated (no longer maintained) version of this map service here:
    2. New layer added: LiDAR-derived sinkholes. Find this in the layer list under "Water". This layer also turns on when the "Karst Potential Map" layout is toggled. The features in this layer are available for the Floyd's Fork basin near Louisville.
    3. Data downloads are now being added for some layers. Currently downloads are available for the geologic map data, oil and gas well data, and the LiDAR-derived sinkholes. For those layers that have data downloads (in shapefile or ESRI geodatabase format) you will see a download icon next to the layer name. Click to either download a zip file of the layer or be directed to a page with instructions for download (mouse-over the icon for instructions).
    4. Search for a place widget (geocoding) has been added to the map interface. This was previously in the tools menu - but is very popular and has been elevated to the map for quick use.
    5. A scale bar has been added. Displays both metric and english units. Located at the bottom left of the map.
    6. The fractional scale has been moved to the bottom of the map interface.
    Updates to the Geologic Map Service (9/17/13)
    1. "Well Number" has been added as a label option to both Oil and Gas well ("Oil and Gas Wells" / "Terminated Oil and Gas Permits") layers.
    Updates to the Geologic Map Service (8/9/13)
    1. Terminated oil and gas permits have been added as a separate layer to the service (under the Oil and Gas layers). This was done to help users distinguish between actual wells that have been drilled and permitted locations that may not have been drilled.
    Updates to the Geologic Map Service (2/22/13)
    1. Added a quick search and zoom to an address or placename of interest. Simply enter information into the search box under the "Tools" tab (under the navigation tools).
    2. Horizontal/deviated oil and gas wells are now designated with an "(H)" next to their label. And deviated wells traces now only display approved permits. Please note that these are only deviated wells that were approved for drilling by KGS, and not all lines are associated with a drilled well record number.
    Updates to the Geologic Map Service (2/6/13)
    Significant updates have been made to this map service, which include the following:
    1. A "What's New?" link in the header. This links to this dialogue.

    2. New (and hopefully improved) printing capability: ESRI has provided some new tools for printing from web map services, and these have been implemented here. Two printing tools are found under the "Tools" tab. One is for printing to a web page (and then to your printer using your web browser and system printing capability) and the other is for printing directly to a downloadable PDF . For each tool, select a desired page size by clicking on the black triangle. Then, click the "Print" text to print to either a new web window or a PDF. The map will print to a formatted page with a scale and title and will maintain the current map scale (the map area will vary by the selected page size). If you want to just print the map image as displayed on the screen, select either "Map Image Only" or "High Resolution Map Image" for this capability. We are working on capability for downloading a georeferenced map image. Though you can always bring the services displayed on this map application into a desktop GIS (ArcGIS, Google Earth) using the instructions provided here:

    3. You can now control the transparency of the raster base layers (topographic map and aerial imagery layers in "Base Layers").

    4. Added LiDAR 5 ft Hillshade map layer from the KY Division of Geographic Information. This layer is toggled on/off under the "Special Raster" section at the bottom of the "Layers" list. LiDAR data is available for about a 1/3 of Kentucky.

    5. Landslide information from the KGS Hazards Section has been added. These data can be turned on by either toggling the data on/off under the "Data Layers" (five types of data are displayed in this layer), or by simply selecting the "Landslide Information Map" from the "Quick Map Layouts". More information about these data can be found at

    6. Bug fixes, improved map service speed, and improved symbology visibility.
