The thermometer on my truck was reading -11 degrees when this picture was taken. As much as it pained me to leave the warmth of my truck, I simply had to venture into the cold (multiple times) to capture this scene in the sky.

This sundog was the most persistent I have ever seen. I initially got pictures of it at 7:40am. My last one was at 9:46am. It would wane and sometimes disappear briefly but then reappear so I got tons of pics of it from different spots. This was my favorite as it was well-defined and the icy pond with steam coming off below provides some interest in the foreground.

Sun dogs are caused by the refraction of light by ice crystals and appear 22 degrees to each side of the sun. I have had a few chances to grab pics of one, always on the coldest of mornings.
