For the past week, sunsets in much of the Rockies along the U.S. / Canada border have been spectacular, but not for a good reason. Particles from several dozen forest fires in this region have colorized the sky into unnaturally beautiful shades and made the air quality rather unhealthy.

And yet, I kept missing my opportunities to capture and document the otherwordly Sun setting behind the smoke-filled horizon, meager selfies notwithstanding.

Until now.

This photograph will go nicely with similarly composed moonrise images I shot last year.
