BackgroundThe 18-km-wide Pleistocene Chalupas caldera is the source of the about 90 km3 Chalupas ignimbrite, the largest known in the northern Andes during the Quaternary (Beate, 1989). The Pleistocene Quilindana stratovolcano is located within the caldera. The youngest intracaldera lava flow are unaffected by glaciation.
