What can I say? I have never before seen a nipple, breast shaped cloud in the sky before. No Mt Rainier, just this breast, and it disappeared in seconds as the wind was moving the clouds very quickly this day. I was watching for the mountain, but just caught the clouds, no mountain.
It's interesting to me how most of the clouds around this special cloud are darker and rough but the breast cloud is silky smooth. Interesting indeed. Nice catch!
