Seen here looking N from the international airport at Arequipa, Perú, multiple edifices of the massive Chachani Volcanic Complex extend ~9 km across the horizon, with Nevado Chachani in the center. The dark hills in the left-center foreground are lava domes and flows on the SW flank of the main complex dated to about 350-400 ka.
