Where on Google Earth #557

Andrew's WoGE #556 looked very hard, but turned out to have enough clues to find the Lena Pillars in a surprisingly short time once I started looking.

No river this time:

So it's my turn again, after finding Andrew's Arabian volcanoes. Volcanoes in Saudi Arabia ought not to be a great surprise, after all the Red Sea is an active spreading rift. Yet we tend to think that deserts and sand dunes are bad enough, I guess - but there are quite a few active volcanoes in Saudi Arabia including one very near the holy city of Medina.

So this time, no desert for a change.

This time I ask for not only WHAT and WHERE it is, but also the underlying cause for it being where it is. Good hunting!

Paul presented us with the edge of the Ennedi Plateau, which I readily admit would have been a lot harder to find if I hadn't already examined the area to find a good spot for a WoGE. I would most likely have chosen a spot a bit further south with either more famous arches and pillars, or maybe a paleoclimatic remnant - or maybe I will do that at some future time?

Anyway, here is the new puzzle. And it is a bit of a puzzle, I think. :)
