There is a legend of three volcanoes in Chile. They form a line, with the tall and proud ice-capped peak of Lanín volcano at one end, and the gently smoking, demure, and shapely ice-capped volcano of Villarrica at the other end. In between the two is the stunted Quetrupillán, and which has a somewhat beheaded look about it. As if someone has removed the top of a once proud peak.
The legend is that Lanín was a proud warrior who loved to gaze upon his lovely smoking lady of Villarrica. But growing between them was a warrior called Quetrupillán, and as Quetrupillán grew larger Lanín became frustrated that his view of the lovely Villarrica was becoming blocked. Frustration grew into anger and in his rage Lanín cut off the head of Quetrupillán.
Quetrupillán means ‘the headless ghost’ and this could be either a quaint story invented by indigenous tribes to explain to their children why these three volcanoes have different shapes, or perhaps it is a story passed down through time by ancestors who witnessed the eruption at Quetrupillán that destroyed the summit cone.
This is something myself and my Chilean colleague are investigating. Actually we are investigating quite a lot about Quetrupillán. But for now I’ll say a little about the trip we did back in March of this year (2012).
Quetrupillán has a famous neighbour – the smoking volcano of Villarrica. It is understandably famous because the ‘smoke’ is a noxious cocktail of magmatic gases escaping from an active lava lake that occupies the summit crater. And because it’s a fairly easy hike up to the summit to look down into the lava lake. Everyone who goes up there comes away moved if not awed by the volcano, as for most this is a truly unique and weird experience. But turn away from the summit and gaze around and the eye is drawn to the superb ice-capped volcano of Lanín, which lies on the border of Chile and Argentina. (In fact the border goes over the summit.) Lanín looks higher and in fact it is, because it sits on a separate (higher) crustal block, but this is not the place to delve into the vagaries of basement geology and discriminating between the little that is known and the large that is speculation.
Few pay any attention to the less obvious and shorter volcano that lies between Lanín and Villarrica. But this is a rather special volcano. This is Quetrupillán.
My Chilean colleague Andres knew of my work on Icelandic volcano-ice interactions, and that I had worked on another Chilean volcano. So he asked me to go on a recce to Quetrupillán to see if there were interesting volcano-ice interactions.
Now I’m not going to give too much away as there’s a grant proposal being written to do further research in this fabulous place! So I’m going to restrict myself to leaving you to enjoy a few images that reveal some of Quetrupillán’s beauty, and hopefully the captions accompanying the images below will say what needs to be said.
