Mt. Rainier's Lenticular Clouds

Special Edition: The phenomenon you see here is a rarity. It does not occur every year, at least not as dramatically as it did this evening. In fact, I would say that in the twenty years I have lived in this same location, I've witnessed it less than half a dozen times, yet these lenticular formations are famous for occurring above the 14,410' summit of Mt. Rainier. They foretell a change in the weather, to be sure, but what a way to bid farewell to summer!
