A river of smoke more than 250 kilometers wide flowed northwest across the Victoria-New South Wales border on December 12, 2006, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite passed over head and captured this image. Bushfires had been burning in the Great Dividing Range Mountains for nearly two weeks. Places where MODIS detected actively burning fire on this day are outlined in red. It’s likely that additional fires that couldn’t be detected through the very thick smoke were burning in the area east of Lake Eildon. According to news reports, army bulldozers were arriving in the area to construct fire breaks in the watershed area north of Lake Thomson, which provides a significant portion of Melbourne’s water supply.
