Licancabur Summit Elevation: 5916 m Latitude:                22.83°S   Longitude:             67.88°W A classically symmetrical conical volcano,  Licancabur has a circular basal plan with a  diameter of ~10 km, and appears to have  been largely constructed in post-glacial  times (compare the pre-Holocene Volcan  Juriques to the east). There is abundant  evidence of recent activity in the form of  youthful lava flows; a well preserved  summit crater, and an absence of glacial  geomorphic features. The cone is made  up predominantly of lavas interbedded  with minor pyroclastic deposits. Young  lavas are particularly well developed on  the western flanks of the volcano and extend for up to 6 km down the regional slope of  about 3° on which Licancabur is built. Levées and flow ridge morphologies are well  preserved on the thick (50-100m), blocky lava flows. Within the 400 m diameter summit  crater is a fresh water lake, about 90 m x 70 m. This is one of the highest lakes in the  world and hosts a planktonic fauna of considerable interest to biologists. A high altitude  diving expedition in 1984 found the lake to be <4m deep with a temperature of 6 °C at  the bottom. Ruins of archaeological interest are present on the rim of the crater.  Little is known about the earliest activity, but as with many of the other centres in this  region, the oldest lava flows extend considerably further than the youngest. Flows on the  west extend for ~12 km from the present centre and their distal portions divide into  several thin flows extending 1-3 km from the main lava body (~9 km from the volcano).  Flank lava flows are the most recent activity from this Licancabur. There are no records  of historic eruptions.
