When the wind blows this drops to the base of the lee side. I think that mine extracts Chromium-rich magnetite from the playa. <br />These strange black dunes are found on both sides of the alluvial fan, and nowhere else. That makes it unique enough that I thought it should be fairly easy to find - and there is only the one mine in the area.Ole Tjugenhttps://www.blogger.com/profile/12465157136272803838noreply@blogger.comtag:blogger.com,1999:blog-5278626342788425855.post-49487116778622434942015-04-09T05:29:10.838+02:002015-04-09T05:29:10.838+02:0037.683 N, 84.437 E

This alluvial fan, draining from the Kunlun and Altun mountains, is the largest alluvial fan in the world (<a href="http://www.atlasobscura.com/places/alluvial-fan" rel="nofollow">source</a>).<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5278626342788425855.post-9201951400118313922015-04-07T08:33:16.895+02:002015-04-07T08:33:16.895+02:00The glacier drains south into a river which runs w...The glacier drains south into a river which runs west and then turns northwest when it meets the desert. <br />The black coating on the dunes confuse the interpretation of shadows. The white stuff is deposited in seasonal lakes, not snow on the tops of the dunes. :DOle Tjugenhttps://www.blogger.com/profile/12465157136272803838noreply@blogger.comtag:blogger.com,1999:blog-5278626342788425855.post-57983322476082370342015-04-07T08:08:11.811+02:002015-04-07T08:08:11.811+02:00Hmmm.

In the original image, ...Hmmm. I'm puzzled. <br /><br />In the original image, there are what I would interpret as shadows to the south of the hills; with north up, that means we're looking at the southern hemisphere, or the extreme southern northern hemisphere. The colors change with season---do the dunes become snow-covered?<br /><br />With the second picture, we now have glaciers, with drainage to the south. Australia is clearly out, and Africa doesn't look so good either (also the comments above). There is dust on the glaciers all the way up to the crest, so there needs to be significant wind present---or a nearby volcano. This should also be a fairly distinctive feature.<br /><br />It isn't a small little obscure desert, so we are probably talking something larger, like the Atacama, Gobi, or Talikman deserts. There is a mine, so Antarctica is out, too, not that the dry valleys are particularly tedious to search.<br /><br />There are no fluvial features I can discern on the original image. The dark stuff (technical term) seems to be flowing northwest to southeast. I would put the prevailing winds from the west, too.<br /><br />So that's where I am. Wandering the globe in search of a weirdly metallic, mined, color-changing dune system downhill (southeast) from some dust-covered glaciers.
