Charles E. Burchfield, Journals, Vol. 51, September 24, 1950

Sept. 24- Dark and cold. It was not until noon that I first noticed the strange yellow light outside. It kept getting darker and darker. The strange hot tawny color at the zenith, had the quality of a yellow August afterglow, yet different. By 2:00 P.M. it was almost like night. In the west deep blue black clouds, then the sky went from Mars violet up to tawny orange- lower clouds white and cold. In the S.E. brilliant yellow light at the horizon.
     Over the radio, we learned that it was a huge bank of smoke from extensive forest fires in western Canada. It lowered the temperature about 10 to 15 degrees below normal. Very depressing as well as awesome.
