Pyroclastic cones and lava domes dot the surface of snow-covered Ghegam Ridge (upper left), located west of Lake Sevan (right) in west-central Armenia. North lies to the upper right in this NASA Space Shuttle image. The volcanoes and associated lava flows cover a 65-km-long, 35-km-wide area west of Lake Sevan and are concentrated along 3 NNW-SSE-trending alignments. Lava flows from the central and eastern clusters flowed into Lake Sevan at the upper left-hand side of the lake.

Snow-capped pyroclastic cones of the Ghegam Ridge volcanic field rise across Lake Sevan from a fishing village on its NE shore. The Ghegam Ridge volcanic field in west-central Armenia covers a 35-km-wide area between the capital city of Yerevan and Lake Sevan. Morphologically youthful lava flows from the central and eastern portions of Ghegam Ridge flowed into Lake Sevan.
