The dormant Volcán Parinacota (6348 m) appears on the right side, Volcán Pomerape (6282 m) just behind its left flank. The hummocky landscape goes back to a 6 km³ rock/debris avalanche originating from a volcanically induced collapse of the slopes of Volcàn Parinacota approx. 8000 years ago. The Laguna the Cotacotani seen in the left portion of the image was influenced by this event. However, its origin is most likely related to glacial processes.
