Mt. Rainier in the state of Washington is one of the Cascade volcanoes that generates some amazing, other-worldly clouds. Because it is so high (over 14,400 feet / 4300 meters) it acts like a giant rock in the atmosphere. Winds blowing over the top sometimes form wave clouds (also called lenticular clouds) in the lee of the mountain. On occasion, these can end up looking like UFOs, flying saucers, or stacks of pancakes. This time lapse set has been a long time in the making -- as I captured enough sequences to get a continuous flow. Visit timeframes-video.strikingly.com/ to see more in this collection.
