Late last week I saw a weather phenomenon that I had never seen before: a fogbow. I drove out of the fog that was blanketing the Gros Ventre River as I was headed toward Kelly, Wyoming in Grand Teton National Park and I looked over to my left and saw a massive fogbow at the base of Blacktail Butte.
A fogbow is a unique weather phenomenon that forms in the same way as rainbows, but because of the tiny size of the water droplets, water isn’t refracted as easily as in a rainbow. Most turn out to be just a simple, white bow, whereas in rarer cases, some have a soft blue or red tint around the edges.
