The Berwickshire coastline is a rugged and untamed stretch of land that is a favourite destination of ours for a refreshing break during a northbound journey, offering ample opportunities for exercise and fresh air.
These breathtaking views along the coast are the result of millions of years of sedimentary rock formation during the Palaeozoic geological era, spanning 85 million years. Thick layers of sandstone make up the cliffs and headlands, while softer mudstone and coal layers, as well as thin limestone layers, are broken down by the waves. The red arch in the middle distance is one of these sandstone layers, gradually eroding into a headland with stacks and arches.
Nearer is a grey limestone outcrop. In Scotland, limestone is not commonly found, and wherever it is present, it is exploited. At one point, it was burnt in kilns to create quicklime, which was used to neutralise acidic soil.
In the distance, you may notice the chimney of the Dunbar Cement Plant, which is situated near limestone layers that can be seen on the shore near Barns Ness and are quarried inland to produce cement.
