There isn’t a sunrise on the Sahara, per se. It doesn’t go from dark to light. It just slowly gets less black and more light until there you are, the sun, rising on the distant horizon, blocked slightly on its dusty horizon by grubby dunes of sand.
We are well moored on a sandy riverside beach by the time the sun sets. Camp is set up (our little make-shift toilet prepared at the end of the little beach) and we sit, our weary group of travelers, on our floating night-hotel, and watch the sun slowly lower over the hills, it’s last few heated rays glistening in the oily Nile water.
