One of the reason I still venture outside on very cold days, is to see something I may not see other days. In this case it was seeing sundogs, I had been seeing them over number of days as the cold temperatures had settled in Banff. The day I got this picture, I went for a quick hike with the hopes of finding a spot where I could get a clear pictures of both sundogs. Once I got the picture, it was a quick walk back to the car before the cold air got to me.
Couple days ago with minus 30 degree Celsius, I got to see a sundogs. Thanks to the ice crystals in the air, sunlight gets refracted. Creating a halo and what looks like two smaller suns, one to the left and one to the right.
