An intricate and detailed drainage pattern of the ephemeral Gascoyne River (dark swath bottom center to upper left) can be observed in this arid region north of the Maeadam Plains in Western Australia. Numerous ephemeral tributary streams feed into the wide floodplain of the Gascoyne River from both the north and the south. Maps show this part of the river as a dry stream channel. The darker, linear features within the various braided stream channels are either an indication of some moisture (hence the darker appearance) or more likely, evidence the floodplain has sufficient moisture to support more vegetation than the surrounding desert landscape.
