The world's highest historically active volcano, 6739-m-high Llullaillaco, sits astride the Chile-Argentina border. The summit, seen here from the NE, is formed by a smaller well-preserved cone that was constructed on an older edifice dating back to the early Pleistocene. A major debris-avalanche deposit produced by collapse of the older volcano extends eastward into Argentina. Growth of the modern cone was completed with the emplacement of a series of young lava flows down the northern and southern flanks.

The world's highest historically active volcano, 6739-m-high Llullaillaco, sits astride the Chile-Argentina border in this NASA Space Shuttle image (with north to the upper right). A well-preserved summit cone was the source of prominent lava flows that are older than they appear in this image. The hilly terrain at the lower right was produced by a major debris avalanche about 150,000 years ago that swept eastward into Argentina and diverges around the north and south sides of the older Cerro Rosado stratovolcano (extreme lower right).

The snow-mantled surface of Llullaillaco volcano is seen in this NASA Space Shuttle image (with north to the upper left). The two youthful looking lava flows with prominent flow levees descending the northern and western flanks of the volcano appeared to be of Holocene, but Ar/Ar dating showed them to be of late-Pleistocene age. The 6739-m-high Llullaillaco is the world's highest historically active volcano.
