Amazingly, the stunning solar phenomena seen in the previous two photos vanished within a few minutes, never to be seen again that day. But all day looking north in front of us, Rainier was putting on its own show of lenticular clouds. The lenticular wrapped around the summit is streaming off to the left (southwest), implying that there are powerful northeast winds at this level (which produce the cloud as they condense when forced upward over the summit). But a second lenticular cloud at upper right is located well above and to the southeast of the mountain, revealing that strong winds higher aloft must be from the northwest.
