Carstensz Glacier
The Carstensz Glacier is near the peak of Puncak Jaya (sometimes called "Mount Carstensz" or the "Carstensz Pyramid") which is a mountain in the Sudirman Range of the island of New Guinea, territorially the western central highlands of Papua province, Indonesia. The glacier is situated at an elevation of approximately and is east of the summit tower of Puncak Jaya. In 2002 the Carstensz Glacier was in length and wide. The glacier is named after the 17th century Dutch explorer Jan Carstenszoon, commonly known as Jan Carstensz. Background. Research presented in 2004 of IKONOS satellite imagery of the  New Guinean glaciers indicated that in the two years from 2000 to 2002, the Carstensz Glacier had lost a further 6.8% of its surface area. An expedition to the remaining glaciers on Puncak Jaya in 2010 discovered that the ice on the glaciers there is about thick and thinning at a rate of annually. At that rate, the remaining glaciers in the immediate region near Puncak Jaya were expected to last only to the year 2015. A 2019 study predicted their disappearance within a decade. The remaining remnant glaciers on Punkak Jaya were once part of an icecap that developed  approximately 5,000 years ago. At least one previous icecap also existed in the region between 15,000 and 7,000 years ago, when it also apparently melted away and disappeared.
