I've seen some pretty unbelievable things but this has me really amazed. The first photo was taken near my home yesterday, which incidentally was passover. The cloud looks like several things to me: a feather, a feather pen and even an angel wing. The cloud was vertical in photo one and no other clouds were in the sky around it.
In the second photo, clouds rolled in and surrounded the "feather" cloud but it appears that the feather cloud has a barrier around it and was not disturbed by the other clouds.
God's amazing creation is all around us!
Blessings to you on this day of remembrance!
