Great photos! I'm envious of your trip.
FWIW story: In a single engine plane once flying from Port Angeles to Redmond, OR, we were on a course around SeaTac headed to pass east of the Rainier summit. SeaTac air control called the pilot to ask him if he was aware that he was headed east of Rainier. He replied that, yes, he was and was changing course to go west of Rainier.
I asked my pilot friend what that was about. He said that normal air flow off of the Pacific creates a huge boiling eddy of clear air turbulence downwind of the peak, to its east. It can be severe on small planes.
