Kızıl Mountain
Kızıldağ is a 3015 m high mountain extending NW-SE between Sivas and Erzincan provinces. Kızılırmak takes its name from Kızıldağ, where it originates from the southwest slopes.
It is located in the Köse Mountains system together with Yıldız Mountain, Asmalı Mountain, Tekeli Mountain and Köse Mountain. This mountain group is called Kızılırmak Arc Mountains or Yeşilırmak Arc Mountains. The northern slopes of Kızıldağ are under the influence of the Black Sea climate. In these areas, forests consisting of coniferous trees and broad-leaved menengic and oak species are seen.
Kızıldağ is the place where the borders of the Black Sea, Eastern Anatolia and Central Anatolia regions separate. Its northern slopes are within the borders of Black Sea, its eastern part is in Eastern Anatolia, and its southwestern slopes are in Central Anatolia.
Glacial forms are seen on the northern slopes of the higher parts of the mountain. During the ice age, circus type glaciers were formed. It is calculated that 9 circus glaciers over 2655 m cover an area of 2.33 km². It is understood from the floor and side moraines that the Kizlarsivrisi Circus is 1500 m long.
The D 200 state highway starting from Çanakkale passes through the Kızıldağ Pass on Kızıldağ.
