4. Useful Links
1. Digital Geological Mapping
Go to British Geological Survey (BGS) ‘Geology of Britain Viewer’ @
http://www.bgs.ac.uk/discoveringGeology/geologyOfBritain/viewer.html
Click on ‘Open Geology of Britain Viewer’
Click on ‘Got to location’ (top right)
Enter location (e.g. Delamere or Beeston) and click search
1:50,000 scale map should appear
Click ‘Geology Key’ to see what rocks are shown (clicking on individual items in the key will give you detailed descriptions
of the formation)
+/- allows zoom in/out (the scale of mapping changes and the level of detail in the geological key also changes to match)
You can click on options for showing bedrock only, superficial/Drift only, or both bedrock and superficial/Drift
Adjust ‘transparency’ to see underlying OS background map more clearly (for orientation)
Grid reference follows the cursor, so you can pin-point exact locations

5. Useful Links
2. Identify water wells and boreholes in the area (only
those for which BGS has records)
Possibly a useful starting point for identifying wells/boreholes for which
more information is required.
Go to British Geological Survey (BGS) ‘GeoIndex’ @
http://www.bgs.ac.uk/geoindex/
Click on ‘Open the onshore Geoindex’
Click ‘Go to Location’ (top)
Enter location then ‘go’
Click ‘Search’ (top)
Select appropriate category (e.g. Water wells) from ‘Select layer to search’
Click ‘Rectangle’
Move cursor to corner of your area of interest and drag across. A list of the borehole/wells in that area will appear. Hover cursor
over item in the list and its position on the map will be highlighted. Use scroll-bar on right to view whole list. List provides basic
details of wells/boreholes and indicates what sort of info (if any) is available on the respective well/borehole log.

6. Useful Links
3. To obtain downloads of individual well/borehole
logs.
Go to British Geological Survey (BGS) ‘Geology of Britain Viewer’ @
http://www.bgs.ac.uk/discoveringGeology/geologyOfBritain/viewer.html
Click on ‘Open Geology of Britain Viewer’
Click on ‘Got to location’ (top right)
Enter location (e.g. Delamere) and click search
1:50,000 scale map should appear
Click on ‘Borehole Scans’ and lots of dots appear (colour coded according to well/borehole depth)
Use info, such as grid ref and depth, from your list of boreholes (from GeoIndex) to guide cursor to well/borehole of interest. Click
over the point of interest and the name/number of the well/borehole appears
Check that it is the one you want and, if available click on ‘Scan Available View Online’ and a copy of the well/borehole log will
download.
Print/Save etc (please note these can only be saved one page at a time i.e. If a log is 8 pages long, you will need to save 8
separate files.
