WOGE #422

After searching in vain for #420, I quickly solved WOGE #421 which was a multiple stratovolcano with very nice lava flows. #421 showed some nice features which helped to locate it. This included shadows (southern hemisphere), snow remnants (high altitude) and a volcanic crater, which together guided me to a volcanic more or less active area of the central Andes.

Now it's time to present #422, which covers a completely different topic in the wide range of geology.
It might not be the hardest one, but as there are some interesting things worth to mention about geology, I'll post it anyway. As you can see I considered a tilted picture as best option.


As usual:
Find the location on GoogleEarth and clearly define it's location (lat/long) for example. You will also have to explain the geology the best you can. Your  prize (and duty) will be to host the next WoGE.

Where on Google Earth #412

Brian led us to the "horizontal waterfalls" at Kimberley coast in northern Australia. Even his oblique image could not stop me from recognizing the place immediately as I've visited it on GoogleEarth before.

As a happy winner I can present yout WOGE #412 which will lead us away from the Australian continent:

Where on Google Earth 409

With a bit of luck, i solved my second WOGE, the Brandberg intrusive granite.
Therefore i have a new task for you, which should not be too complicated:

Geology from space

While looking for the WOGE riddle on google earth I found this wonderful geology-satellite image at
27° 8'50"S / 16° 9'55"E in Namibia:


I really like the kind of leaf-like structure.

Where on Google Earth #406

After the completely dry landscape in #405, the next WOGE contains slightly more water, enjoy!

For #405 I was looking at some NE-SW trending mountain ranges in very arid areas like around the Gobi desert and along the ancient silk road, as it was supposed to have historical importance. But at some point I decided to go for lower elevations as many of the asian mountains seem to have snow covered tops. History, wide and dry riverbeds combined with not too high mountains finally guided me to egypt, where it was just a matter of finding the right spot without too much sand in the picture. My guess about a hidden tomb as historic feature turned out to be wrong as it showed roman quarrys where the word porphyry was first used to describe rocks.

The Overburden Blog: Where on Google Earth #405

Hi guys,
Found it:
27°12'60.00"N /  33°15'60.00"E
After searching the ancient silk road, i decided to go for egyptian tombs which lead to the right place even thou it's no tomb.

This WOGE shows the site of quarrys, active during ancient egyptian and roman times. Andesite–dacite porphyry and granite was mined to produce ornamental stones. The paths on the mountain slopes in the second picture are slipways where dimension stones were transported in ancient egypt.

Here you can find more information about ancient quarrys in egypt.

Up to now, I never thought I would start blogging, but as I found the "Where on GoogleEarth" game (WOGE) on geologic features here. I started this one to be able to take part in the game in an easy way.

I may post also some other geology related stuff or pictures in future.
