Yesterday morning was busy at Mt. Rainier. It's so big and massive that it makes its own weather. See that "lenticular cloud" it made? And then a mean little cumulus clould floating by. And it is a little tricky to see at this resolution, but you see that "blob" just under and below the left edge of the dark cloud? That's an airliner, taking off from SEATAC.
What a view the people on the left side of the plane had!
