Qori Kalis is the largest outlet glacier of the world’s largest tropical ice cap, the Quelccaya Ice Cap, which lies on a plateau 18,670 feet (5,691 meters) high in the Andes mountains of south central Peru. In 1978, the glacier was still advancing. By 2011, the glacier had retreated completely back on the land, leaving a lake some 86 acres in area and about 200 feet (60 meters) deep.
