After 185 episodes I’ve finally won a Wo(G)E !! The bright orange colours led me immediately to the Namib Desert, it was just a matter of time until I found where two dune sets interfered at right angles to give the pattern in the image.

Now the only problem is that in the past week I have been having huge fun submitting images to the new multi-authored geopathology blog. It is devoted to landscapes that are pathological “in the sense of being developed or expressed in such a degree that is extreme, excessive, or markedly abnormal” according to the blog’s founder Dr Jerque. If you are a devotee of Wo(G)E and haven’t seen geopathology then please drop by, I’m sure you will find it of interest. Anyway, as a consequence of this, and never expecting to actually win a Wo(G)E, I have just blown most of the places I would have used for a place for you to find. Typical.

The image below has an eye altitude of about 12km and note that north is to the right. Vertical exaggeration is set to two and it is slightly oblique to make the structure a little more obvious.

So I need to know the latitude and longitude of the image, a general locality name and an explanation of the geological feature(s) illustrated. The first person with the correct answers gets to host the next edition.

No Schott rule on this one – everyone just dive in. Click the image for a larger version.
Where on (Google) Earth #186

  1. Found it! It’s location is:

    24°19’54.79″S and 70°18’21.95″W near Sierra Remiendos in Chile. As far as a geological explanation, i don’t know the area that well but as a guess it looks like either a very linear thrust front with the hangingwall to the west (top of the image) or a N-S strike-slip fault (due to it’s linear nature). The fault also appears to be counter regional; i.e. thrusting east instead of west.

  2. It also has some great looking alluvial fans showing the sharp scarp slope…

  3. Congratulations. We have a winner. It is in fact the Atacama Fault, a major normal / strike-slip fault south of Antofagasta in northern Chile. It takes up some of the oblique component of the subduction of the Nazca Plate along the the Chile trench.

    Dan, it is over to you ….

  4. Thanks hypocentre, that was a good one. I’ll be posting the next one shortly.
