Unique geological wonder Symphony of the Stones near Garni, Armenia

"The ""Basalt Gorge of Awan"" is located in the valley of the Azat River below the town of Garni about 30 km east of Yerevan. Basalt is usually dark gray to black. Since the basalt arises volcanically, it consists for the most part of a fine-grained matrix due to the rapid cooling. If the cooling of the lava takes place with a delay, the contraction often results in meter-long angular basalt columns (columnar basalt) that are perpendicular to the cooling surface, preferably with a hexagonal geometry."
