Kind of a happy holidays shot.
I have learned that rime is white ice that forms when the water droplets in fog freeze to the outer surfaces of objects. It is often seen on trees atop mountains and ridges in winter, when low-hanging clouds cause freezing fog. This fog freezes to the windward (wind-facing) side of tree branches, buildings, or any other solid objects, usually with high wind velocities and air temperatures between −2 °C (28 °F) and −8 °C (18 °F). I am pretty sure this is a rime photo with nice morning ambient lighting -- it was surprisingly foggy during my weekend visit to Northwest Montana.
Taken off of Highway 2 west of Kalispell and not too far from the turnoff to Kila, Montana, 12-03-10.
