GeoExposures — recording temporary exposures and enhancing our knowledge of the geology of the UK through the GeoExposure community website.

Here today, gone tomorrow

The geological community in the UK has long recognised that scientifically important information revealed in temporary exposures of bedrock and superficial (Quaternary) deposits is frequently 'lost to science'. This is largely due to the temporary nature of the exposures and the inability of the geoscience community to respond at short notice.

Temporary exposures only!

GeoExposures is only concerned with the recording of temporary exposures, such as trenches, pipelines, foundation excavations, road cuttings and embankments. It is not aimed at documenting natural exposures (e.g. inland and coastal cliffs, quarries, etc.) nor with the conservation of geological sites. For further information on these, see:

How to log a temporary exposure

Share your observations about temporary geological exposures using our iGeology mobile app.

Using the 'points of interest' category, simply record the location and geology of the site (e.g. bedrock, superficial or human-made deposits) as accurately as possible and submit your record along with a photograph.

If you would like to provide more detailed descriptions such as this example provided by JBA consulting then please contact us via our enquiries team and we will be delighted to discuss it further with you.

Submissions will be moderated by a BGS geologist, but will not be quality controlled or scientifically endorsed by the BGS.


Do not enter sites without the permission of the land owner or person responsible; safety is your responsibility.
