I haven't been so active lately, often having found the location only long after the NEXT puzzle was posted.
But Paul's WoGE #541 turned out to be surprisingly easy when my first hunch turned out to be correct!
So it's my turn again, and I hereby present yet another round thing:
I think the Schott rule would be superfluous this time.
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.
