Mt. Rainier looked "angelic" with a halo-like cap cloud, but these clouds are anything but heavenly; they are formed by strong upper level winds, making for some dangerous conditions for climbers. These clouds usually indicate a change in the next day's weather. Sure enough, we did not see the mountain the following day, it was socked in by low clouds. Many high mountains "make their own weather". We heard that the mountain is visible only 80 days out of the year, so we were happy we had an unobstructed view the day before this photo was taken. I was excited to see it look like this too!
