They're sometimes mistaken for aliens, but really, it's just a sign rain might be on the way.
Luke Meyers just recently published this time lapse video of a rather strange-looking lenticular cloud over Mt. Rainier last March. It's a good illustration of how they form -- the clouds look stationary but there's quite a bit of movement in them as air rises just enough to saturate, then dries enough as it sinks to "go invisible" again.

SEATTLE -- Some of the people on their way into Seattle Wednesday evening got quite the hello from Mother Nature as lightning struck two different jets as they approached Sea-Tac Airport.
University of Washington student Owen Craft was out in the University District trying to film lightning strikes as a thunderstorm moved through and caught the two massive bolts as they passed through the planes' fuselage.
"I was stunned for a second because I couldn't believe what I just saw," Craft said. "After the second (plane) got hit, I knew I was on to something spectacular!"
Those who were up early enough Sunday morning in Surrey, B.C. and happened to look up were treated to a spectacular scene in the heavens that looks like something straight out of the imagination of a futuristic Hollywood alien blockbuster film.
In actuality, it was the combination of two rather routine events that just happened to have impeccable timing:
A sunrise (one for the ages on its own) …and a plane descending through a solid, stable cloud layer.
CHEYENNE, Wyo. (AP) - A bizarre sheet of wispy clouds undulating over the Teton Range enchanted tourists and even veteran employees of Grand Teton National Park.
Drivers stopped along the park's main highway Thursday morning to gaze in awe and shoot photos of the rare phenomenon hovering over Grand Teton mountain. At 13,775 feet above sea level, the Grand Teton is the highest point in the Teton Range.
The mystery surrounding a white, milky rain that fell across Eastern Washington and parts of Oregon and Idaho Friday has a new theory, although I'd call it more of a tweak of the previous theory.
The event coated vehicles and windows in more than 15 cities, including Spokane, the Tri-Cities, and Hermiston, Oregon. Initial thoughts of the source originating as volcanic ash from a distant eruption or debris blown from summer wildfire-scarred terrain were quickly disproven.
