Smoke over 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.
