Alvand

Alvand is a subrange of the Zagros Mountains in western Iran located 10 km south of the city of Hamadan in Hamadan province. Its summit has an elevation of 3,580 m (11,750 ft). The main body of the Alvand range extends for about 50 km from east to west, while their maximum north–south width is about 30 km. Formed as part of the Zagros orogeny in the late Jurassic and early Cretaceous, the mountains rise sharply from the surrounding plains and are scored by many deep valleys. The mountains are mostly granite and diorite, which are types of intrusive rock.
