"Volcán Domuyo is a 4709-m-high Argentinian stratovolcano of late-Pleistocene or possibly Holocene age (Moreno 1985, pers. comm.). At least 14 dacitic lava domes and other eruptive centers were constructed within a broad 15-km-wide caldera, and at least another 5 lie outside the caldera. The largest of the latter is Volcán Chanque-Mallín on the ESE flank. It is truncated by a 4-km-wide caldera and contains a resurgent dome."  -Smithsonian Volcano Archive
