laval flow in the Aragvi valley. A second phase 137–70ka with large scale effusive activity included the "Pyramidal Peak" Volcano which dammed local rivers with lava flows. From 90ka on activity formed Didi-Nepiskalo and the Ekisom and
Khorisar domes. The third phase less than 30ka with evidence that it continued into the Holocene formed Eastern Khorisa and Ploskaya Vershina. Activity of East Khorisar Volcano spans both stages and created lava flows in the

The Patara-Nepiskalo volcano is strongly degraded by glacial action and may have had a caldera. Other volcanoes are Sharkhokh, Northern Shadilkhokh, and Southern Shadilkhokh in the western Kaidon range and the lava flows created by the latter two volcanoes between the
