Smoke pouring from numerous fires in the
northwestern United States and Canada
obscured the ground over much of the Pacific Northwest and Great Plains region. The smoke (gray pixels) was so thick it filled a number of the valleys in the mountainous regions of the northwest. Some of the smoke appears to have been drawn eastward along the southern edge
of the low-pressure cell visible over
Manitoba (in the high-resolution version of this scene).
