group of young basaltic stratovolcanoes in western Argentina
near the border with Chile and south of Lanín volcano.
Background:The Huanquihué volcano group consists of a NNE-SSW-
trending chain of stratovolcanoes of Pleistocene age, some of
which lie along the border. A Holocene compound cinder cone with
three nested craters up to 400 m in diameter that occupied a
valley NE of Cerro Huanquihué and a tuff cone constructed within
glacial Lake Epulafquen lies at the northern end of the chain.
Growth of this Holocene tuff cone, La Angostura ("The
Narrowing"), created a peninsula that formed a narrow channel
connecting Lake Epulafquen and Lake Huechulafquen. A very recent
lava flow from the base of the Achín-Niellu cinder cone (also
known as Cerro Escorial) traveled north into glacial Lago
Epulafquen, forming a prominent lava delta. The Escorial lava
flow is an extremely youthful flow that diverted local drainages
and formed new lakes. A radiocarbon da
