Apparently this phenomenon occurs a few times a year, and it creates a remarkable looking cloud formation. See some photos at Mt. Rainier puts on a show.
Here's the explanation:
The cloud is formed when warm, moist air runs into the surface of Mt. Rainier. The mountain's topography forces the air upward, which cools and condenses the air -- turning it into a cloud.
As the air sinks back on the other side of the mountain, it dries out and the cloud dissipates. That's why it just hangs over the summit area.
(Although it looks like it is "hanging" over the mountain, air is continually flowing over the summit.)
Thanks Sis.
Wow! It's so good to see Rainier again. I used to live in Tacoma, Wa., and we once drove halfway up the mountain to the Paradise Visitors Center. It's truly a spectacular place. Thanks for the photos!

That must have been nice, TB. I just can't imagine what it would be like living in such a scenic area.
