A WALL of dust stretched from northern Queensland to the southern tip of eastern Australia on the morning of September 23, 2009, reports NASA’s Earth Observatory, while the Washington Post reports dust blanketing Sydney.

From NASA: Strong winds blew the dust from the interior to more populated regions along the coast. In this image, the dust rises in plumes from point sources and concentrates in a wall along the front of the storm. The large image shows that some of the point sources are agricultural fields, recognizable by their rectangular shape. Australia has suffered from a multiple-year drought, and much of the dust is coming from fields that have not been planted because of the drought, said Australian Broadcasting Corporation News.
