Where on Google Earth #355

Since I was able to locate the brilliant blue waters of the Bahamas in Felix Bossert’s #354, it falls to me to give you somewhere to look for.

As a newcomer, I have chosen something quite (very?) easy, but apparently the pace of the game is slow right now, so the Schott Rule is not in effect.

Where is this: Where on Google Earth is this?

This should be a quick game, so good luck.

EDIT: (2012-09-30) It appears that my judgement was off, so here is a bit of a hint: This is found on the edge of a major structure in the southern hemisphere.

EDIT2: (2012-10-07) The structure is in Africa. It is easily found using your favourite search-engine, should you know what to search for.

Hi Martin, this is just a test as new websites sometimes do not show up comments. So it looks like as if it’s working. 🙂

Martin: recently we are a litte bit in slow motion. It could be we need 2-3 weeks to get your picture solved. It is not extremely easy as the shadows are not clearly visible, so the hemisphere was not clear. Your hint helps a lot…

Maybe we have a problem with our rules. As on this game only the first one wins, very often you are looking hard for a picture, and someone is faster. In this case you have invested a lot of time, but you do not get credit for it. On other similar games, the race goes one week, and the comments are not visible. So everybody finding (and correctly commenting) the place gets 2 points. Everyone finding the place after a hint has been published gets 1 point. With these rules newcomers also get credits and can develop their skills from game to game.

Maybe we should change our rules accordingly.

Whereongoogleearth.net is a great game (with a lot of participants), but has a geographical approach. So you have to find more human build locations lake castles, theaters, companies etc. The places are always carefully chosen and do have some interest. As most of the time, the places to be found have been in the actual media, Whereongoogleearth.net is more a Google-Search-Game. I find it much easier. If you identify the actual media interest in the picture you need not more than 10 minutes to find the place. If you miss this actual relevance and you have to find it by the traditional search of clues in the picture it can take some time to find it as the scale of the pictures are much smaller than in our game.

Maybe a mixture of both games (with a geological content of couse) would be an improvement.

Having some trouble getting comment onto your page currently……

The locality is on the edge of the vast Okavango Delta, a huge inland delta system though not even the largest one in Africa it seems. 97% of the water that flows into the plain is lost through transpiration, evaporation and aquifer recharge, a quite remarkable statistic. There are numerous interesting geological features in the area including the tectonic structure that forms the ‘Panhandle’ which has channeled the Okavango river valley through steep sided vallyes towards the delta. There are extremeley interesting hydrodynamics in the delat created by varying riverbed elevations across the huge fan area and also very interesting soil properties given the deposition of salts and other minerals. However I struggled to find anything specific to the locale other than a reference to a ‘Gumare Fault’, Gumare being the town to the west of the picture.

Hope this comment gets posted and I’ll start thinking og my own locale should I be the winner

Nicely done. There was nothing specific to this locale, other than I found the pattern of rivers pretty, and the general interest of the Delta itself, which did not appear in the list of WoGE locations.

What is also interesting is the dunes located not far west, between Gumare and the Namibia/Botswana border.

I look forward to hunting for your location. 🙂

(The problems may have been the links, which I have now approved.)

I will need to see if I can find an online source for this, but every few years the delta switches which direction gets the most water. At the moment, I believe that the majority flows into the north of the delta, but about 15 years ago, it was mostly flowing into the southern area.

My source for this was a very interesting lecture given by Dr Terence McCarthy of Wits University a couple years ago. Not sure where or if it is documented, since I have lost access to most of the academic sources that might be of interest.

WOGE#356 is now online here http://holelotofnothing.blogetery.com/

Martin FYI the Okavango Delta was the subject of WOGE#270, albeit the location was on the eastern side of the fan. You may like to download the .csv file which contains the placemarks of all previous WOGE challenges for your information, its also hugely interesting reviewing the explanations of features across the globe.

You can obtain the file from Felix Bossert’s blog, the link is on the right hand side of the page.

Hmmm…. Must have missed it. I did look at it, which meant I did not use the Great Zimbabwean Dyke, which was my first idea.

But some amazing stuff on there. 🙂
