Where on Google Earth #471

Veidos gave us a very nice glacial deposit in WoGE #470, which while rather small had more than sufficient clues to alow me to find it in a very short time. Since I found it so quickly, I decided to wait a week before posting the answer so that others could have a go at it. But unfortunately it seems I am the only one who can recognise moraine shapes on sight?

For WoGE #471 I decided to stick with the subject.


There are glaciers here, but I think that the geology of this area is well enough documented that a correct answer should include a little bit more than just the glaciers.

No Schott rule on this one, unless you know where it is and decide to wait on your own initiative. ;)

As always, post a comment with latitude and longitude and write something about the (geologic/geographic/hydrographic) feature in the picture. If you win, you get to host the next one.

Previous WoGEs are collected by Felix on his blog and a KML file.

    Puncak Jaya or the Grasberg mine (to the left)
    04°04′44″S 137°9′30″E
    Puncak Jaya is the highest mountain in Indonesia (4,884 metres) and is the highest point on the central range, which was created in the late Miocene Melanesian orogeny, caused by oblique collision between the Australian and Pacific plates and is made of middle Miocene limestones.
    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 with significant retreat since the 1850s - they're disappearing at a rate of seven metres thickness per year and should be vanished within this year.

    Knowing a little about Ole's WoGE-interests, the nearby Grasberg mine should be a focus in this WoGE. This gold (the largest in the world) and copper (the third largest) mine was found by Jean Jacques Dozy in 1936 in an expedition that scaled Puncak Jaya.

    These southern highlands with a little left green made me think in something tropical - the (almost) W-E orientation allowed me to eliminate South America and Africa (this time I was right and begin in southern Asia - luck was on my side, this time - finally! :)

    And ... The overburden (700 kt/d) remains in the highlands, up to 480 m deep and covering 8 square kilometres.

    Congratulations, Luis!

    And it was a good deduction, too. :)

    Thanks!

    Lately my deductions have been through the mud ...

    Anyway, WoGE #471 is here: http://woge-luis.blogspot.pt/2015/02/woge-471.html!
