So it's my turn again...
Andrew's WoGE #572 was one of those where finding out what it IS and then searching for that was far more efficient than searching for WHERE and then find out WHAT - in this case, the Henbury Meteor Crater field in Australia.
This time there is a location you can find, and a lot of geology to find too. There is even a chance that you could find it by searching for THAT kind of geology, too!
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.
