Located approximately 50 kilometers northeast of Tehran, Mt. Damavand is an impressive stratovolcano that reaches 5,670 meters (18,598 feet) in elevation. Part of the Alborz Mountain Range that borders the Caspian Sea to the north, Damavand is a young volcano that has formed mostly during the Holocene Epoch (over approximately the last 10,000 years). The western flank of the volcano includes solidified lava flows with flow levees—“walls” formed as the side edges of flowing lava cooled rapidly, forming a chute that channeled the hotter, interior lava. Two such flows with well-defined levees are highlighted by snow on the mountainside.
