Gegham mountains

Gegham mountains, Armenian: Գեղամա լեռնաշղթա are a range of mountains in Armenia. The range is a tableland-type watershed basin of Sevan Lake from east, inflows of rivers Araks and Hrazdan from north and west, Azat and Vedi rivers from south-west and Arpachai river from south. The average elevation of the Gegham mountain range is near 2500m. The range is of volcanic origin including many extinct volcanoes. The range is 70 km length and 48 km width, and stretch between Lake Sevan and the Ararat plain. The highest peak of the Gegham mountains is the Azhdahak, at 3597m. They are formed by a volcanic field, containing Pleistocene-to-Holocene lava domes and cinder cones. The highland reaches a height of 1800–2000m up to 3000m in the dividing ridge. ()
