Flowing southeastward in a graceful arc, a plume of smoke from fires in northern Canada—and perhaps from other fires in eastern Alaska— stretches across this image centered on Manitoba, Canada, west of the southern tip of Hudson Bay on July 25, 2004. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of the plume snaking its way toward Lake Superior, at bottom right. The smoke from fires in Alaska and Canada has reached southward all the way to the Gulf Coast.
