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.

Previous WoGEs are collected by Felix on his blog and a KML file, along with the "rules".
Good hunting!

  1. A whole week has passed, and no takers.
    Maybe I should post another picture? A smaller area would only show where in the world it is, and that's about what a larger view would, too!

  2. Looks like the Karst areas in Guilin: http://woge-felix.blogspot.com/2011/01/where-on-google-earth-256.html

  3. It does, doesnt it?
    I will confirm that this is a kart area, and that it is not in Guilin.

    Since there is a LOT of this kind of karst landscape, I picked one with a distinguishing feature. There's another special case (but a different feature) just to the west of this image.

  4. OK. I give in. I found this some days ago but couldn't find much on the geology. I recognized it as karst, and there's a lot of it in the general region so it took a couple hours of a gridded search pattern to find it. But, I figured someone else would get it and know a bunch about it. And then I promptly forgot all about it, getting wrapped up in other things. But it's still here... so I'm grabbing it! :)

    Hubei Province, south central China.

    It's no longer easy for a total amateur like me to find information like I used to because Google did away with the Wikipedia layer on maps, and there's very little left of it in Google Earth. Those georeferenced wikipedia links were very educational for much more than geology. (a rumor I found says the wikimedia foundation turned down a google offer to buy them, so google is "doing evil")

    About all I could find is that the river is the Qing Jiang, to the south west is the city of Lichuan, to the south east is Enshi.

    Near Lichuan is Tenglong Cave, possibly "the longest monomer karst cave system in the world." No idea what "monomer" means in this context. All I could find on that was a discussion asking exactly that question in reference to this Wikipedia article.

    I also found that to the north is Xiaozhai Tiankeng, "Heavenly Pit", the worlds deepest sinkhole.

    I would guess that the karst has a name as well, and there is a Wikipedia entry on notable karst regions, but none listed for China seem to include this area that I can tell.

    I would also guess the canyon passage has a name, but I could not find it. Must be quite a sight in person. And since it's in the center of the image I supposed it to be the focus of the search, but I just can't find anything on it.


  5. The canyon is called "Enshi Grand Canyon" or "Mufu Grand Canyon", and is considered one of the most spectacular areas in China. So it must be quite a place!

    As I said it's a typical Chinese karst region, but somewhat more spectacular than most. I am sure that there is information on the geology somewhere to be found, but workload and lack of Chinese reading skills have so far prevented me from finding it. So I let this one go as pure geomorphology. ;)

  6. Excellent. Now that I know what to look for...

    Found this nice video: http://www.youtube.com/watch?v=QEMdJ15dqqg

    Several more linked from there.

    Now to go browse my list of "possible WoGE's" to see what I have to stump everyone. I should have one posted by the end of the day (for me, that's about 12 more hours).


  7. WoGE #424 is up! Good luck everyone.
