Sixty-eight fires were affecting an estimated 94,107 hectares (232,543 acres) in Canadas Yukon Territory on 30 July 2009, according to thedaily situation report from the Canadian Interagency Forest Fire Centre. Several large blazes were pouring out thick smoke plumes when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite passed overhead and captured this natural-color image. Places where MODIS detected active fire are outlined in red. This image is cropped (at left) along the border with Alaska (visible in large image), where even smokier fires are burning. The smoke from these fires and others in Russias Far East are veiling the entire Arctic with haze.
