WOGE #470

It has been a while since I succesfully searched for a WOGE. #469 took a while too, as i was searching in the wrong mountain system at the right latitude for quite a while (The Atlas mountains and nearby mountain ranges extending as far as Tunisia, which include some similar structures but with less water. E.g. 34° 5'30"N /   8°22'15"E).

The nice tectonic structures of WOGE #469 however were found within the Sulaiman fold and thrust belt in Pakistan.

For people who enjoy searching more than reading my thoughts: WOGE 470

(Its rather small, but i had to exclude something from the picture to make it a bit harder...)

Have fun searching.

As usual:
Find the location on GoogleEarth and clearly define it's location (lat/long) for example. You will also have to explain the geology the best you can. Your  prize (and duty) will be to host the next WoGE.


  1. Ouch. I found it already, by a combination of luck and deduction. So I will now shut up until next Thursday. If there are no answers by then, I will post mine.
    In the meanwhile, I will try to make a structural analysis of my last puzzle. ūüėä

  2. Since it is Thursday again,

    64.33°N 15.52°W

    Moraine at the end of Fláajökull near Höfn, Iceland.

    This kind of moraine forms when a steep dry glacier flows onto a broad plain. At maximum extension the glacier toe forms a semicircle, leaving behind concentric ridges as it retracts. If it were any less steep the ice supply would vary much more, giving more widely spaced ridges. If there were a significant meltwater flow, the resulting meltwater river would erode the moraine ridges, or form a glacial lake (see the nearby Heinabergsjökull and Svinafellsjökull for examples).

    Two things led me to think this had to be in SE Iceland at first glance: There is a field right next to the edge of the moraine, which looks like it has been used for grazing over a period of more than a few hundred years (it is evenly green, the kind of green that comes from centuries of good fertilisation). That excludes most of the world, except Norway and Iceland. Norway has very few moraines of this shape, the only one I know of is B√łdalsbreen. The mountains around B√łdalsbreen are a lot higher and steeper than this as I know very well, my family is from that area. That leaves Iceland. From the direction of the moraine and presumably the glacier that formed it, somewhere close to the SE coast of iceland was a safe bet.
