The Quelccaya (also known as Quenamari) Ice Cap is the second largest glaciated area in the tropics, after Coropuna. Located in the Cordillera Oriental section of the Andes mountains of Peru, the ice cap covers an area of with up to thick ice. It is surrounded by tall ice cliffs and a number of outlet glaciers, the largest of which is known as Qori Kalis Glacier; the terrain surrounding the ice cap features lakes, moraines, peat bogs and wetlands and features a rich flora and fauna, including birds which have been observed to nest on the ice cap. Water from Quelccaya eventually nourishes the Inambari River and the Vilcanota River and is an important source of water.
