After leaving El Paso, our road branched off at an angle of about two points to the westward of the river, the city of Chihuahua being situated nearly a hundred miles to the west of it. At the distance of about thirty miles we reached Los Médanos [The Dunes], a stupendous ledge of sand-hills, across which the road passes for about six miles. As teams are never able to haul the loaded wagons over this region of loose sand, we engaged an atajo of mules at El Paso, upon which to convey our goods across. These Médanos consist of huge hillocks and ridges of pure sand, in many places without a vestige of vegetation. Through the lowest gaps between the hills, the road winds its way.
