The Guelta d'Archei Oasis

If you searched for the Sahara desert on Google Maps, you'd find a little speck that's located in the desert. That little speck, though, is a geological and zoological wonder. If you were trekking through the desert, if you saw it in the distance you would think that it's just a happy mirage... It’s called the Guelta d'Archei and it is an oasis, (actually a guelta). A guelta is a type of wetland you will typically find in the desert. And what happens there is a beautiful miracle.
