What can I say about the dunes of the Sahara, other than that they are incredibly beautiful. We stayed in a tented camp near Merzouga, which is in southeastern Morocco, about 30 miles from the border with Algeria, and at about 2,400 ft elevation. One evening we went to the Erg Chebbi dunes to watch the sunset.

As the sun went down, the color of the dunes changed,

And the edges of the dunes became more pronounced.

Here is a quintessential photo: a line of camels going by (tourists, not nomads!)
