I found Gord's WoGE #494 quite quickly, a very interesting location in Argentina with sufficient visible clues to make it a relatively simple search.
My summer vacation starts in 3 hours, so I don't really have the time to search for a "perfect" WoGE this time. With the new update, Google Earth itself has a lot of interesting geography highlighted, which makes it a little bit harder to find something that will take at least a few hours to find.
This one shouldn't be hard to find, I believe.
But there is a LOT of geology here - metamorphic, economical, structural, glacial, morphological, erosional...
Previous WoGEs are collected by Felix on his blog and a KML file.
