Basalt canyon Studlagil in Iceland🇮🇸
The place is famous throughout the world, listed in a huge number of textbooks and reference books on geology. Just recently, no one even suspected about this place, because quite recently, namely until 2007, the Yokla River flowed in the place of the canyon, but after the construction of a hydroelectric power station, it became shallow and the canyon appeared before the eyes of people in all its splendor.
