The glacier-capped Alney-Chashakondzha complex, its summit partially obscured by clouds in this NASA Landsat image (with north to the top), is one of the largest volcanoes of the Sredinny Range. It consists of two large Pleistocene andesitic stratovolcanoes, 2598-m-high Alney on the north and 2526-m-high Chashakondzha on the south, both capped with andesitic lava domes. The Kireunsky lava flow from a vent on the eastern side of the complex was erupted about 2600 years ago.

Glacial canyons descend from the western side of Alney volcano, which along with Chashakondzha volcano, forms one of the largest volcanic complexes of the Sredinny Range. Alney is one of the few large stratovolcanoes in the Sredinny Range known to have been active throughout the Holocene, with more than 30 documented pyroclastic deposits. Cinder cones on the east flanks of Alney and Chashakondzha volcanoes also erupted during the Holocene.

The Kireunsky lava flow was erupted from a vent on the eastern side of the Alney-Chashakondzha volcanic massif (background) about 2600 years ago. The lava flow was erupted from a vent east of Alney volcano on the divide between the Kirevna (far right) and Pravaya Kirevna (left foreground) rivers. Tephra from the Kireunsky eruption almost immediately overlies a tephra from a cinder cone to the south.

The Levaya Belaya lava flow was erupted from a cone 5 km ENE of the summit of Chashakondzha volcano. Flow levees are visible in the middle of the photo, and the Levaya Belaya River has cut a channel along the northern margin of the flow. The Levaya Belaya flow was radiocarbon dated at about 2610 years ago, and tephra from this eruption almost immediately underlies a tephra from another nearby cone 5.5 km east of the summit of Alney volcano.
