From the Exploration Unit
Do yourself a favor and google image search "The Ennedi Desert."
I'm VERY familiar with most of the major rock formations and arches found in the southwestern United States. So when some interesting formations from the Ennedi desert popped up in a few searches and I didn't recognize any of them, my curiosity was piqued.
This place is a treasure of inspiring rock formations and vistas. Seems like every corner of this desert is a shot for a Star Wars location.
Located in northeastern Chad the region has a sparse population of semi-nomads, chiefly Muslims who speak the Dazaga dialect.
Will definitely be referring to this the next time I need to design an alien landscape.
I pulled images from these three websites: LINK and LINK and LINK
