Just what is Alpenglow? I do know that it is the pink light you see on the mountain peaks. Galen Rowell had many great photos like that. What I am wondering is the pink or red showing on lower non-snow covered mountain at a lower elevation, say 1400 feet also Alpenglow? What about the pink light on clouds. Is this also Alpenglow? I am referring to this pink coloration under a clear sky with high visibility and the sun not shining through clouds. I do not see this term used in meteorology which I find somewhat puzzling. Perhaps the term is only used by nature photographers and artists. Dictionary.com mentions it as a rosy glow on snow-covered peaks at dusk or dawn on a clear day. Is this definition correct?
