Just heavy smoke from wildfires on the west side of Grand Teton National Park. 2 weeks ago, the view over Jackson Lake in the park was eerie as the moon set through the smoke. The coppery red glow looked very similar to a lunar eclipse in tone, and reflected off what little water was left in the lake (normally, the waterline would have been about 20 feet in front of my position in this photo, but the massive drought in the west has visibly taken it's toll in this image.)
