Meandering a dune maze

…the course of the Nile describes a huge “S” curve- one of the largest meanders in the world. Here the name Nubia is imprinted on the map.

-Nubia: Corridor to Africa, William Adams

KhairAllah’s route was usually dead straight and he only meandered once, in the Nubian Nile’s Delgo Notch. Here the river’s northern course inexplicably turns 90° due east for ten miles, then due north for thirty miles, then back 90° to the west before bending again sharply north, leaving in the void a tangle of paths criss-crossing amongst the dunes like a mixed-up corn maze. When lost and if cloudy with no sun to steer by, one can go in near circles, as did we for much of the day.
