Luis' WoGE #527 was a bit of a puzzler. I spent a long time searching the highlands of Madagascar before finally finding the mountains on the border between Mozambique and Zimbabwe - and even having found the place it was difficult to find good information on the geology. Maybe it would have been easier if I could read Portuguese?
Anyway, here is a somewhat more populated place for WoGE #528:
This one really ought to have been posted about a month ago.
As always, the first person to post the position and whatever is interesting about the geology/hydrology/geowhatever in this location, wins the privilege of hosting the next WoGE.
Previous WoGEs are collected by Felix on his blog and a KML file.
