Tip with the most strange shadow

All businesses - large or small, have a shadow. This also applies and for the mountains. One peak though is basically a strange phenomenon - he throws no shadow on the ground  and in  the clouds. 

Mount Rainier is located 87 km from Seattle. The peak is 4392 meters high. In the absence of other mountains around, on a clear day it can be seen even from Portland, Oregon.

In Cloudy   morning, however, with the help of rising sun  top casts a shadow  over of the surrounding clouds.

This only happens in the fall and winter, when the sun is at a particular position.
