Arintica

Arintica is a stratovolcano located in Arica y Parinacota Region of Chile, near the border with Bolivia. It lies north of the Salar de Surire. The volcano has a main summit in the north, a slightly shorter southern summit and a subsidiary peak in the west. A glacier valley lies between the summits. The height of the snowline is . Stage II moraines found on Arintica have altitudes ranging from on the southern flank to on the eastern flank. On the western flank they reach altitudes of . In total, five glaciers surrounded Arintica and drained into the Salar de Surire. Presently, rock glaciers are active on the mountain.
The volcano was constructed in two phases and postglacial lava flows have been found by Landsat imagery, but they are unsampled. A previously identified southeastern lava flow has been later identified as a debris avalanche. A dacitic lava dome is found southwest of the volcano and is named Calajata. In a 2011 hazard map Arintica was considered a potentially dangerous volcano of Chile. Whether the volcano was active in the Holocene is contentious. A belt of "Polylepis" woods surrounds the volcano.
