Geological Summary. Little-known glacier-covered Yanteles volcano in southern Chile is at the corner of a volcanic massif located 60 km S of the city of Chaiten, with higher eroded peaks about 5 km E and along a ridge extending 10 km SW. Several Holocene tephra layers have been attributed to this volcano. There were reports of an eruption at the time of the 20 February 1835 Chile earthquake, and Sapper (1917) stated that previously unseen black areas were observed there after the 1835 earthquake, but the nature of this activity is not clear.
