Lenticular Clouds Over Mnt Ranier

One of the coolest sites I have ever seen are these very strange cloud formations unique to Washington's Mount Ranier. They are called lenticular clouds and are formed when the combination of warm air rising and cold air falling creates these circular outworldly patterns. Like SUN DOGS they always make me feel that we are being visited by aliens cause it would be just the kind of disguise that a spaceship would use. They certainly are hypnotic.
