The appearance of two of those patches is shown in Figs. A, B. In Fig. A, the circle is modest and still covered with dead grass, whereas in Fig. B, dead grass within the center with the (larger) circle has disappeared, presumably by means of breakage and transport by wind, as well as the center is bare. Fig. C shows how such circles appear inside the aerial view, with circles displaying some degree of central bareness, and and getting nevertheless covered with dead grass. Both Figs.
