Where on Google Earth # 482

Felix' WoGE #481 looked impossible at first glance. It showed a karst area, most likely in China since that is where this specific type of karst surface is most common. Looking closer I saw that it was not quite as impossible as I first thought, and from then it didn't take very long to find the correct location.

This WoGE is similar: It is a dune. Yet there are enough distinguishing features to place it in a fairly limited area, and I have included one feature making the location unique.

 
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. If you do not have a blog of your own, many of the regulars are very willing to help by hosting your puzzle.

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

After a week has gone, and with Easter holidays coming up, I think it is time for a hint:


I followed a stream upriver to the source, and I think I may have found the source of the black coating on the dunes. It also explains why there is a mine in such an inhospitable area, the source area is even worse!

Where on Google Earth #478

Trying to keep up the speed after finding Felix' WoGE #477, I present WoGE #478 without waiting for confirmation.


This is more a phenomenon than an occurrence - and recent work suggests that the traditional explanation is wrong.

Where on Google Earth # 476

Yet again my unusual memory helped me pinpoint a WoGE in record time, and it is my turn again. Felix gave us the famous lithographic limestone quarries near Solnhofen, famous for the very many beautifully preserved fossils - including what is perhaps the most famous fossil of all, the  Archaeopteryx lithographica.

So this time there are no dunes, nor glaciers. Maybe.

In order to win the next challenge, you will have to clearly define the location of the picture (by lat. long for example) and find some words to the geology on display.
