The photo above showing a breathtaking lenticular cloud hovering over the Sierra Nevada range was captured at sunset in Stateline, Nevada (adjacent to Lake Tahoe). Lenticular clouds (altocumulus lenticularis) are formed when relatively stable air flows over mountains or elevated terrain -- often observed on the lee side of mountain ranges. These lens-shaped or almond-shaped clouds tend to remain nearly stationary with respect to the terrain. Photo taken this past April.
