Köroğlu Mountains

The Köroğlu Mountains rise south of Bolu and Gerede in northern Anatolia. Their volcanic heights include Köroğlu Tepe on the Aladağ massif, while the Devrez and Gerede streams mark the separation from ranges farther north. Moist air from the Black Sea supports forests on the mountain slopes, with beech and fir in sheltered areas and pines on drier ground.
