A message from Erwin Sevens:
As a incidental visitor, wandering through geology related webpages, I stumbled upon the WoGE 184 contest. Intrigued by the beautiful phenomenon shown on the image and loving to browse around the planet with the Google Earth application, I could not resist trying to find out where it was located.
So, with a little bit of luck, I pretty quickly found the location in Bolivia. The “crater” like structure is a synclinal depression formed of Cretaceous sediments interlayered with basaltic deposits. It seems to be the place to see dinosaur tracks and a tourist attraction for hikers.
So, according the rules of the contest, it is now my turn to challenge you. Ann and Chris have kindly agreed to host.
The region where I grabbed this picture is one of the many examples how aesthetically beautiful geology can be. It is taken from a eye height of 19.33 km and the top of the image is within 30 degrees of North. And no, it is not on Mars.
So, what do we see and where is it located?
Note from Chris: I think Erwin might be a little bit evil, but we’ll have to see. Although I’m tempted to waive the Schott Rule for this one, I think I’ll leave it in force for the time being. Therefore you need to wait one hour after the post time [20:45 GMT/15:45 EST) to answer for each Wo(G)E round you’ve won in the past.
