The glacier-capped Nevado de Chachani volcanic complex lies immediately north of the city of Arequipa. The central part of the 6057-m-high complex contains multiple vents along an arcuate line. Pleistocene lava domes form the glacier-covered northern end of the complex in this NASA image. A prominent lava-flow complex at the bottom-center part of the image with fresh-looking flow levees was erupted from the 8-km-wide lava shield of Pampa de Palacio of late-Pleistocene to possibly Holocene age.
