Natural History of Upper Teesdale

3 - Bedrock Geology

The significance of its geology figures prominently in Upper Teesdale’s place within the Moorhouse – Upper Teesdale National Nature Reserve and the North Pennines Area of Outstanding Natural Beauty (AONB) which coincides with the UNESCO-designated North Pennine Geopark. Numerous sites and features within the Dale are scheduled as Sites of Special Scientific Interest (SSSIs) specifically for their geological importance.

Whereas there is much of interest in the rocks, fossils and minerals themselves, an understanding of this geological diversity is also vital to fully appreciating the ecological, social and economic character of this beautiful Pennine valley.
