"A chain of dominantly basaltic cinder cones erupted along two NE-SW-trending fissures at the head of Puyuhuapi fjord comprise the Volcanes de Puyuhuapi. The larger group of four cones lies on the western side of Puyuhuapi fjord and fed lava flows that traveled SE to the sea. The second lineament formed a chain of four smaller cones between the head of the fjord and Lake Risopatrón to the north. The two fractures are related to the regional Liquiñe-Ofqui fault zone. The Puyuhuapi cinder cones are extremely well preserved, suggesting a very young age."  -Smithsonian Volcano Archive
