In Papua there is the highest peak in the Sudirman with snow-capped mountains, perhaps you would not believe if you hear it. To be sure please you visit this place, Peak Jayawijaya or abbreviated as Puncak Jaya memepunyai higher reaches approximately 4884 meters above sea level and allow the area covered by eternal snow.
Long ago, Jayawijaya Peaks was the deepest of the sea,
For mountain climbers, climbing the ranks Jayawijaya Mountains is a dream. Imagine, in one of the top of the mountains are the highest point in Indonesia, namely Carstensz Pyramide with a height of 4884 meters above sea level.
Do not be surprised if a top-class mountain climbers the world is always racing to climb one of the points included in the top row of the seven continents. Moreover, the existence of eternal snow peaks are always covered, it makes more passionate desire to attain.
But, who would have thought if the snowy peaks that were once part of a very deep ocean floor!. Guinea began to take shape at 60 million years ago. At that time, the island is still on the seabed formed by sedimentary rocks. Intensive precipitation originating from the continent of Australia in a long period of time produces a new land that is now called Papua. At that time,Australian continent to the other continents separated by oceans. In the sea of the northern part of New Guinea rocks that settles that part of Australia will appear at a later date. Intensive deposition of this kangaroo continent, eventually lifting the stone into the sediments above sea level. Of course, this removal process based on the geological time scale with a speed of 2.5 km per million years.
This process is compounded by the occurrence of plate collision between the Indo-Pacific plate with the Indo-Australian on the seabed. Plate collision resulted in the island arc, which also became the forerunner of the islands and mountains in Papua.
Finally, the appointment process is ongoing due to sedimentation and tectonic events along the sea bottom, within a period of millions of years of producing such high mountains can be seen today.
Evidence that the high mountains of New Guinea and was once part of the deep seafloor can be seen from the fossil remains in rocks Jayawijaya.
Although located at an altitude of 4800 masl, fossilized sea shells, for example, can be seen in limestone and clastic rocks contained in the Jayawijaya Mountains. Therefore, besides being a paradise of the climbers, Jayawijaya Mountains is also a paradise researchers geological world.
While the separation of mainland Australia and Papua by the sea starts from the end of the ice age that occurred at 15,000 years ago. Melting of ice into the ocean in the end separates the mainland of Papua with the Australian continent.
There are still many secrets of the rocks Jayawijaya untapped. Moreover, the age of Guinea is still considered young, so the process of appointment of the island continues to this day. This is also the reason of the mention of Papua New Guinea to Guinea, which means it is an island that is still new.
While the presence of snow on some peaks Jayawijaya, believes will fade away like that of Mount Kilimanjaro in Tanzania. The loss of the only snow that is owned by the mountains in Indonesia was caused by global climate change is happening in the tropics.
