Geological folding

This image captures a dramatic view of Glentornan Fold in County Donegal, Ireland—a textbook example of geological folding where layers of rock have been compressed into a striking arch over millions of years. A group of hikers stands jubilantly atop the formation, celebrating nature’s artistry, while one person below mirrors their enthusiasm from a boulder at the base. The fold’s alternating gray and rusty bands reveal the immense tectonic forces that shaped this region during the Caledonian orogeny. Framed by steep grassy valleys under an overcast sky, this scene perfectly blends human adventure with ancient Earth history.
