While Puncak Jaya's peak is free of ice, there are several glaciers on its slopes, including the Carstensz Glacier, West Northwall Firn, East Northwall Firn and the recently vanished Meren Glacier in the Meren Valley (meren is Dutch for "lakes") [REF].
The glacier on Puncak Trikora in the Maoke Mountains disappeared completely some time between 1939 and 1962 [REF].
