Wales may be a relatively small nation, but it has a huge geological heritage. It has attracted geologists since the very earliest days of geological exploration, and is still considered to be a prime destination for field excursions. 

Over 700 million years of geological history can be seen in exposures across our mountains, valleys, sweeping landscapes and coastal cliffs. Volcanic rocks and slates tell the tale of fiery, turbulent times, whilst sediments packed with fossils show evidence of changing environments and sea-levels. Rich coal seams and mineral ore deposits gave rise to the rich mining and industrial history of Wales. 

As part of the festival we thought that we would share a suggested geological walk itinerary for the beautiful Pembrokeshire coastline, written for us by Cindy Howells. We hope it isn't too long until we can visit this area again.

The SWGA was founded over 60 years ago and enjoys a monthly programme of winter talks and summer field excursions across the whole of south Wales and the surrounding counties of Wales and England. We produce a range of publications including numerous guides to the local geology, many of which are available to download from our website. We are an exceedingly friendly group of amateur and professional geologists and guests are always welcome at out meetings. so why not come along and give us a try?  Full details of us and our activities can be found on our web site at www.swga.org

Now that autumn is with us, we would normally be enjoying our lecture series. We aren't going to let a global pandemic get us down and so we have started to have some lectures via zoom with an opportunity before the lecture for a group chat just as we have always done. Last Saturday, Alan Bowring gave an excellent talk entitled: Cribarth - a view from your desktop and we have recorded it so if you missed it, follow the link below to go to our YouTube channel to watch in your own time!

Its almost September already but there are some welcome signs of the SWGA getting back to normal... a little bit anyway! Have a look at our news letter to learn about a first tentative field meetings, our postponed (and first by Zoom!) AGM and other articles which we hope you will find of interest.

The current Covid-19 lock-down has sadly disrupted our usual program of lectures and field trips this year. In keeping with the unusual times, this newsletter is a little different as it contains articles from our members as well as news  to ensure we still keep a little geology in our lives! You can download our latest enhanced newsletter here.

Take care everyone and we'll look forward to seeing you all again "on the other side"!

It has been a long time since the SWGA website had an upgrade and we have started one on the 22nd of January 2020... and has, as of 1st February been substantially completed

The site is now responsive to the device you are using. On large screens the full menu will be displayed, on smaller screens the menu option will give you access to all of the information

Please let us know via the contact form if you have any issues with the refreshed website

The coastal section at The Bendricks is a Site of Special Scientific Interest because of the dinosaur tracks exposed here. It is the best site in Britain for dinosaur tracks of the Triassic Period and should be preserved for all to see and study.

Please do not collect or damage the footprints. This site is protected by Law Please report anyone you see removing the rock to the Countryside Council for Wales, the Geology Department of the National Museum of Wales, or the Geologists' Association South Wales Group.

The colourful rocks of Penarth were formed over 200 million years ago. They tell a fascinating story of changes in climate and sea-level. You can download an information sheet here to help you understand the things that you can find


The cliffs are very unstable so it is important to keep well away from them, and not to hammer at them.

In many places in the South Wales Coalfield we find the remains of the plants which made the coal. For many of us these are fragments that we struggle to understand as part of a whole organism, but with the help of Rhian Kendall (Geologist, Artist and former president) you do not need to imagine any more you can see them reconstructed in full colour

PLEASE NOTE: This itinerary is an extract from a book partly compiled during the 1990s. The text and photographs reflect the geological knowledge of that time as well as the accessibility of the locations.

Please ensure that you ask permission from landowners to visit any of the locations mentioned in this text, which are on private property and that you are suitably equipped for rough terrain and fickle local weather.
