Where on Google Earth #467

Felix' WoGE 466 led to an amazing christmas-tree-like rock formation in a canyon on what may be Mexico's most polluted river.

Is this game getting too complicated? I don't know, but it looks as if there is a small group of people with a "special talent" for drawing together all the little clues and then ending up in more or less the right location. Those of us who have found many will continue to do so, because we know how to do this. And of course some of us are just to stubborn to give up if we don't find it right away!
We can only hope that keeping the game running will bring in more new players, and more new talented puzzle-solvers. I notice that among the "top ten WoGE-finders", two of us are relative newcomers having played less than 100 rounds since the first find (I don't like to call it a "win").

Since we are still in the extended holiday time, I will continue with a modification of  Felix' modified Schott rule:

"Quadruple Schott Rule with max 5 days".  This means every player has to wait the amount of hours, four times the amount of his/her previous wins until he or she is allowed to solve the game, but not longer than 5 days.

5 days since today is a Tuesday, giving newer players until noon on Sunday Jan. 4th (CET, GMT+1) before the field opens.


There is no connection to the season in this location, at least as far as I am aware. Just north of here is an unusually clear example of something that I would have liked to include, but the features are just too small even if these are among the only ones visible on a satellite photo. Take a look at them when you have found this location! If this puzzle has not been solved within a week, that will be the first hint.

Find the picture on Google Earth and clearly define it's location (Lat. Long. for example). You will also have to explain the geology on display the best you can.

Edited for clarification on December 31st, post date is still December 30th.

And now, some more pictures. Just because I want to. :)

First the overview, showing the tempting green lagoon. Water this green tends to be laden with silt from glacial runoff, which indicates that the temperature is rarely much higher than freezing. At least that is my experience from many baths in lovely green Norwegian lakes.
 

Closeup of the parallell ridges, showing the rectangular pattern - polygon ground controlled by linear contrasts.

The "corner" with overlapping ridge directions I suspect that the shape of the boundary between the two sets will be some kind of climate record.

And this is what polygon ground looks like, except that in most cases each "cell" is at most a few meters across. This must have been developing for a long time, much longer that e.g. on Svalbard. The precise mechanism that forms these polygons is subject to speculation, but permafrost is certainly involved.

Where on Google Earth #465

Matthew's WoGE #464 was tricky to find, I had eliminated all continents and was just about to start on the islands when a picture of a lemur pointed me straight to Madagascar and the threatened Lake Alaotra.


 There are many lakes in the world, and surprisingly many deserts. This time I have found a view with at least three interesting things, of which two are geology. One of them is related to my work, and so is the other but in a very different way.



If you want to have the honour of posting a Christmas WoGE, you should hurry up. :D


 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.

Where on Google Earth #463

It is my turn again after finding Felix' WoGE #462, a segment of the Kunlun Fault showing displacement of crossing alluvial fans.

Deserts are always popular in WoGE, so this time I will go for something more humid:

WoGE #461


Felix' WoGE #460 was solved as quickly as my WoGE #459. :)

To stick with the theme, here is a round thing:

It is a little smaller than the last one, so I have hopes it will last more than an hour or so!

WoGE #459

The memory works in mysterious ways, which helped me solve Felix' WoGE #458 very fast. In fact it took me less than a minute to realise what it had to be, the rest of the time was trying to remember the name of the place so I could find it on the map. :D

These days, the eyes (and webcams) of Norway are on the mountain "Mannen" which seems to be about to fall into the valley below (see http://blogs.agu.org/landslideblog/2014/10/29/mount-mannen-1/ for more info).

So, thinking about landslides, I present WoGE #459:

WoGE #456

Luis' WoGE #455 seemed difficult at first, until I realised that the horizontal layers might be volcaniclastics.


So following that thought, here's a volcanic WoGE:





Location, name and date please!

WoGE #454

A preemptive posting this time, since although I solved Luis' WoGE #453 by accidentally looking at Dek Island in Tana Lake, Ethiopia, he hasn't confirmed it yet. But weekend starts very soon, and I expect to be very busy next week, so here it is:


I will only add that I have no idea how that thing ended up where it is!

A week later, a hint seems to be needed!

This is the same thing, looking due east:


Unlike glaciers, these things do not have a habit of forming on mountain tops.

Another week, another hint:

This is outside the area shown in the first two, but should at least get you to the correct continent.

WoGE #452

I came back from summer vacation and found Felix' WoGE #451 relatively quickly. I was looking in the wrong hemisphere for a short while, until I managed to get all the visual clues to fit together. Then it became obvious that it had to be New Zealand. :)


This WoGE contains something geologic inside something geologic. If you find one, it should be easy to find out what the other one is, and what is so special about the smallest feature.


Desert again... ;)



I invoke the Schott Rule again for this, since one feature only occurs in a limited area.

WoGE #449

Yet again I solved one of Luis' WoGEs.

Extremely high relief, little large-scale lithological variation and especially no consistent sedimentary structures, together with very variable resistance to erosion led me to look for an extinct volcanic island - I had my summer vacation on La Gomera a few years ago, and that is a typical example. This time it was Madeira, which is definitely on my holiday list. ;)

This place however is NOT on that list:





This one should be easy, so I invoke the Schott Rule.

Intermezzo

I have been a bit busy lately so I haven't had time to search for WoGEs. But I came across THIS today, which I would like to share. It seems I can't embed it here, so you will have to follow the link.

Enjoy!

WoGE #444

My turn again?

Luis' WoGE #443 seemed very familiar, I was sure I had come across it somewhere. It took me a while to remember where, and then I found the very obvious Waw-an-Namus volcano in Libya. Zooming in on the crater removed most of the desert references, which made it a bit more difficult. :)


For WoGE #444, I decided to stay with the desert theme:

 
Where and what is it? And is there really any correct information on the geology to be found?

WoGE #441

It's my turn again, after finding Kubilay's Aurora Crater.
That one took me longer than it should, the geology and vegetation pattern led me almost directly to the right spot once I started looking: Scattered deciduous forest, light dusting of snow on north slopes, seemingly semi-arid climate, and volcanism: Nevada, near the border with California. Mono Lake is not far from here, and that area has almost exactly the same features.


So here's a new one - and it's a single dune. :)





Yes, it's a small area. And there is a good reason for that. Have fun!

WoGE #436

I seem to be on a roll here, with challenges that somehow fits my way of thinking. Felix' WoGE #435 is a case in point, the size and shape of the fields together with lots of forest, power lines and a rocky-shored lake pointed me to Finland or Sweden; it was Finland.

This one is NOT in Scandinavia:

WoGE #434

Luis' WoGE #433 seemed almost impossible at first glance, but there were enough clues to lead me to New Zealand even without noticing the deleted image information.

Sticking with an eruptive theme, I hereby present one that I suspect really IS hard:

I have zoomed rather close, but that is because there is nothing more to see!

A warning: If you activate shorelines, this one isn't marked - at least not in the correct place. The Wikipedia tag is in a third location.

WoGE #432

Luis made an almost impossible challenge with WoGE #431, the Cherbakul lake where the major parts of the Chelyabinsk meteorite have been found. I foundi it through inept navigation, I thought I was searching somewhere else!

After such a cold and wet location it is time to go for a drier place. Maybe not so hot, though - at least not all year!


I like desert locations, it's so easy to see the major geologic elements. And I like mines, because it's easy to find in-depth geologic information. So here's a mine in a desert.

WoGE #429


Luis had an ineresting WoGE #428, one I am sure everyone has seen photos of. Yet it proved deceptively hard to track down, even when starting on the right continent!

But enough outliers and inselbergs. Here's a hole.



Where is it, why is there a hole now, and what is the geology of the area?

Schott rule applies, due to the historig/geologic/something else significance of this hole. Original posting time 3/10/2014 10:33 UTC/GMT +1 hour.

I have deliberately zoomed in rather close to make it a little less easy.

WoGE #427

It's my turn again, and as usual I struggle to find something that is bothe hard enough to find and interesting enough geologically speaking. Which means I should be able to find out something about the geology myself, preferrably without resorting to at-work literature searches: If you need a subscription to read about the geology, it's unfair.

Matthew's mysterious table mountain took a while to find. I searched in all the wrong places first, and finally found it in another "wrong place". A geological map showed what it is, but really opened more new questions as to why it is where it is. Maybe I should go have a look at it in person?

One thing that I'm reasonably certain of, is that it's not an "outlier".

This one IS an outlier. I don't think it will be hard to find, and it's well documented so Schott's rule is in effect.

Where on Google Earth #425


Brian's WoGE #424 was one of those cases where it was harder to find information than to find the location. I blame the nearby mercury mine for having fogged the brains of the mappers; every search I tried ended up in the mine. Still there were good structural clues which helped find out what and where it was.


This one also has some clues as to the location. Finding out exactly what it is may be harder, though - at least I hope so. :)

Where on Google Earth #423

Veidos presented an unusual landform in WoGE #422, the Köfels structure in Austria. The most obviously notable features of this, at least on a map view, are the almost circular outline and the narrow gorge the river has cut through the huge landslide deposit.

Without further ado, here is another narrow gorge:




As always, the task is to find out where it is, what it is, and post it in a comment here.
Whoever first supplies the (or "a") correct answer, gets to host the next WoGE.
