Tskhouk-Karckar, Shield volcano in Syunik Province, Armenia.

Tskhouk-Karckar is a shield volcano in Syunik Province with a broad, dome-like structure reaching 2620 meters elevation. Its wide basalt lava flows create the characteristic flat shape that spreads across the landscape.

The volcano formed through multiple eruptions over long geological periods that deposited extensive lava flows. Repeated basaltic activity gradually built up the current formation over time.

Petroglyphs lie buried beneath the youngest lava stages, broken by earthquake activity; they point to human presence between the 4th and early 3rd millennium BC. Radiocarbon dating of graves inside the flows gave 4720 ± 140 years BP. The last eruptive stage appears to have driven people from the area, which was resettled only in the Middle Ages.

Visitors need sturdy hiking equipment and good physical fitness, as the terrain is challenging. Weather conditions can change quickly in the area, so proper planning is important.

The volcano sits directly on the border between Armenia and Azerbaijan, making it geographically significant. The basalt formations clearly show the mark of repeated volcanic activity over time.
