Smoke from wildfires blew across Canada’s Northwestern Territories and Nunavut Territory in late July 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on July 25, 2011.
Wildfires near McLeod Bay created thick smoke observed by MODIS on July 23. Over the next couple days, winds carried the smoke hundreds of kilometers eastward. In this image, smoke forms a serpentine pattern across Nunavut and Hudson Bay.

Thick smoke choked the skies over Manitoba, Ontario, and Hudson Bay on Tuesday, July 24, 2007. Thick swaths of smoke hundreds of kilometers across stretch eastward over Canada’s land and water. The smoke can be distinguished from the nearby clouds by the difference in color. Whereas clouds are bright white, the smoke is dingy gray.
