The featureless area at the top left is the smooth water surface of Bositeng Lake, a large lake in the far northwest of China. The slightly curved sand spit offers one indication that the monotonous area is a lake. Spits such as these are common features near lake shores and are produced by waves and longshore currents. In contrast to the smooth surface of the lake is the intricate pattern of a dune field on its south side. Darker surfaces next to and between some of the dunes are wet.
