A Guide to Cork City's Geological Heritage

The Glen has a lot to offer.

The Glen As the ice sheets melted, the meltwaters cut deep river valleys into the Devonian and Carboniferous rocks. The Glen River and River Bride on the northside are likely examples of such rivers that are now much less energetic and more idyllic than they would have been a few thousand years ago. But the effect of these strong forces is as visible as the Glen itself. A small canyon valley to the east of Blackpool, the Glen is a beautiful park with grass fields, benches and adventurous trails. Around the valley there are remains of former sandstone quarries, now covered in thick vegetation and more recent sediments and soils. Gravel pits from where Quaternary sediments were extracted also existed in his area. Today, the area is recreational and a fantastic natural amenity for the City.

Layers of sandstones, siltstones and mudstones in the park.

At the western side of the Glen the valley opens up and offers an environment that will make you consider whether you are in the City or on a hill walk in West Cork. It is also here where tilted layers of sandstones, siltstones and mudstones can be closely examined.
