I came back from summer vacation and found Felix' WoGE #451 relatively quickly. I was looking in the wrong hemisphere for a short while, until I managed to get all the visual clues to fit together. Then it became obvious that it had to be New Zealand. :)
This WoGE contains something geologic inside something geologic. If you find one, it should be easy to find out what the other one is, and what is so special about the smallest feature.
Desert again... ;)
I invoke the Schott Rule again for this, since one feature only occurs in a limited area.
For any new players to Where on (Google) Earth, simply post a comment with latitude and longitude and write something about the (geologic/geographic/hydrographic) feature in the picture. If you win, you get to host the next one. Previous WoGEs are collected by Felix on his blog and a KML file.
