Nemrut (volcano) the region. The collision of these plates began in the Middle Eocene and closed the stretch of water, which in the Mesozoic formed the Tethys Ocean. Nemrut, along with three other extinct volcanoes of eastern Turkey: Ararat, Tendürek and Süphan, is located in the area of a complex fault, which runs along the boundary of the Arabian and Eurasian plates in the territory of the Armenian Highland. It is the westernmost of these volcanoes, the only one that remains active, and generally the only volcano in Anatolia, which erupted in the historical period. Nemrut is located 10 km north of

The first European to climb Mount Barney was Captain Patrick Logan, who reached the East Peak
